Executive Summary
The purpose of this report is to provide information to system owners and stakeholders to
satisfy the regulatory requirements of the Safe Drinking Water Act (SDWA) including the
Drinking Water Quality Management Standard (DWQMS); Section 81 of the Clean Water Act
(CWA); and regulatory reporting required under O. Reg. 170/03 - Section 11 and Schedule
22.
This report is a compilation of information that helps to demonstrate the ongoing provision
of a safe, consistent supply of high quality drinking water to customers located within the
City of Guelph and the Gazer Mooney Subdivision (located in the Township of
Guelph/Eramosa).
Water Services is a municipally-owned and operated water utility, established in 1879. The
Guelph Drinking Water System (Guelph DWS) consists of water supply and treatment
facilities and a water distribution system. The Guelph DWS is a Class II Water Treatment
Subsystem and Class IV Water Distribution Subsystem.
The Gazer Mooney Subdivision Distribution System (Gazer Mooney SDS) is a Class I
Distribution System supplied with water from the Guelph DWS. Guelph Water Services is the
Operating Authority for this system owned by Guelph/Eramosa Township.
Both the Guelph DWS and the Gazer Mooney SDS are required to comply with the Safe
Drinking Water Act (SDWA) and other regulations as well as requirements contained in
Permits to Take Water (PTTW), Municipal Drinking Water Licences (MDWL), and Drinking
Water Works Permits (DWWP). Having met the quality management system requirements of
the SDWA, Guelph Water Services is an accredited Operating Authority with an up-to-date
Operational Plan (OP). The OP is available upon request from Guelph Water Services.
Guelph’s Source Water
The source of Guelph’s drinking water is a series of 21 operational groundwater wells and a
shallow groundwater collector system. These sources consists primarily of true groundwater
sources, with some “groundwater under the direct influence of surface water with effective
in-situ filtration” (GUDI-WEF) sources (Carter 1, Carter 2, Arkell 1, Arkell 15 and the Arkell
Springs Glen Collector System).
The water system is operated to meet daily, seasonal, and other operational demands
(including fire demands) with various combinations of supply sources in operation at any
given time. A total of 17,160,654 cubic meters (17.2 billion litres) of water was treated and
pumped to the system in 2019. The average daily water demand was 47,015 cubic metres
2019 Annual and Summary Report
ii
(47.0 million litres). The maximum daily production of water in 2019 was 58,441 cubic
metres (58.4 million litres) and occurred on November 30, 2019. A large watermain break
occurred on this day, resulting in an increased amount of water pumped. Please see the
Results of Emergency Response Testing section for more information. The minimum daily
production of water in the same time period was 32,477 cubic metres (32.5 million litres)
and occurred on December 26, 2019.
Water Treatment and Distribution
All water provided to the Guelph Drinking Water System and the Gazer Mooney Subdivision
Distribution System was treated with sodium hypochlorite (for chlorine disinfection) with
some sources also using UV treatment, two sites using sodium silicate for dissolved iron and
manganese sequestering and one site using green-sand filtration for manganese removal.
All of the water supplied was continually tested and met all regulatory standards. City of
Guelph Water Services maintained the drinking water system in a fit state of repair and
followed best industry practices during the repair and maintenance of the system.
The City of Guelph has approximately 44,000 fully metered water service connections,
557.3 kilometres of underground watermains, and a population of approximately 131,7941.
The Gazer Mooney Subdivision has approximately 72 fully metered water service
connections, 2 kilometres of underground watermains, and an approximate population of
200 people.
Complying with Regulations
As the Operating Authority for both the Guelph DWS and Gazer Mooney SDS, Guelph Water
Services is annually inspected by the Ministry of the Environment, Conservation and Parks
(MECP) for compliance with regulatory requirements. There were four incidents of non-
compliance associated with the Guelph DWS in 2019; the Gazer Mooney SDS had no
incidents of non-compliance. Through the 2018-2019 MECP inspection, Water Services
received an 89.42% score for the Guelph DWS and a 100% score for the Gazer Mooney
SDS.
In 2019, Guelph Water Services reported three Adverse Water Quality Incidents (AWQIs) in
the Guelph Drinking Water System – please refer to section b) Adverse Water Quality
Incidents.

audits help facilitate continual improvement of Water Services’ processes and programs
through implementation of corrective actions.
Water Services continues to implement:
• Recommendations of the 2016 Water Efficiency Strategy.
• Source water protection based on a MECP approved Source Water Protection Plan.
• Arkell Springs Forest Stewardship Project investments (to protect the Arkell Wellfield’s
source water quality).
• The Lead Reduction Plan in accordance with the regulatory relief provisions of the
SDWA.
• Facility asset management and infrastructure reviews to optimize priority projects.
• A robust backflow prevention program overseeing 2,902 properties with 6,603
backflow prevention devices installed.
Details of ongoing and emerging water quality, supply/treatment, and distribution initiatives
are outlined in section h) of this report and include successful programs related to: water
conservation and efficiency, Arkell Springs forest stewardship, source water protection, lead
reduction and frozen services prevention and monitoring.

team members held drinking water certificates to operate and maintain the water system.
In 2019, Water Services maintained full scope accreditation to the Drinking Water Quality
Management Standard (DWQMS) Version 2.0 after a successful on-site verification audit,
conducted by the third-party accreditation body - NSF International Strategic Registrations.
This full accreditation satisfies part of the requirements under the Municipal Drinking Water
Licensing Program.
Water Distribution System
The distribution system (including watermains, valves, fire hydrants, services, and meters)
serves a population of approximately 131,7942 within the City of Guelph. All new system
components meet NSF 613 requirements or approved equivalents and are installed and
maintained in accordance with approved industry standards. Water system customers are
fully metered and billed in accordance with the Water and Wastewater Customer Rates and
Charges by-law.
The Guelph Drinking Water System distribution system is comprised of the following
infrastructure:
• 6.38 kilometres of 900-1,050 mm diameter water supply aqueduct;

• five underground storage reservoirs with a combined approximate capacity of 48,000
cubic metres (48 million litres);
• three water towers with a combined approximate capacity of 11,200 cubic metres
(11.2 million litres);
• 557.3 kilometres of buried watermain with a diameter < 900 mm;
• 4,286 watermain valves;
• 2,809 fire hydrants; and
• approximately 44,000 water services and water meters.
Guelph Source Water and Treatment Facilities
The source of Guelph’s drinking water is a series of 21 operational groundwater wells and a
shallow groundwater collector system. The drinking water sources consist primarily of true
groundwater, with some “groundwater under the direct influence of surface water with
effective in-situ filtration” (GUDI-WEF) sources. The GUDI-WEF sources include: Carter Well
1 and 2; Arkell 1; Arkell 15; and the Arkell Springs Glen Collector System.
The Guelph Drinking Water System uses 12 per cent Sodium Hypochlorite (that is NSF 604
certified) for primary disinfection for the following 11 sources:
• Downey Well
• Burke Well
• Park Well 1 and 2
• Emma Well
• Dean Well
• University Well
• Queensdale Well
• Helmar Well
• Calico Well
• Water Street Well (UV treatment available on site)
12 per cent Sodium Hypochlorite along with ultraviolet light treatment is used as part of a
multi-barrier primary disinfection for the following ten sources:
• Arkell Wells 1, 6, 7, 8, 14 and 15
• Arkell Springs Glen Collector System
• Carter Wells 1 and 2
4 NSF/ANSI Standard 60: Drinking Water Treatment Chemicals - Health Effects
2019 Annual and Summary Report
Page 5 of 182
• Membro Well
NSF 60-certified Sodium Silicate, used for aesthetic purposes to sequester dissolved iron
and manganese is also used at Helmar Well and Queensdale Well.
In total, Water Services operates and maintains 31 facilities.
The replacement cost of the Guelph Drinking Water System is estimated to be $620.3
million or approximately $4,578 per capita (2019, based on 2017 projected population).
The Guelph Drinking Water System operations are funded directly from the sale of water,
with minor additional funding through government grant programs. Property taxes are not
used to fund the operation, maintenance or capital renewal of the system.
A total of 17,160,654 cubic meters (17.2 billion litres) of water was treated and pumped to
the system in 2019. The average daily water demand was 47,015 cubic metres (47.0 million
litres). The maximum daily production of water in 2019 was 58,441 cubic metres (58.4
million litres) and occurred on Nov 30, 2019. The minimum daily production of water in the
same time period was 32,477 cubic metres (32.5 million litres) and occurred on December
26, 2019.
In 2019, all regulatory microbiological and chemical quality samples were taken by certified
operators and tests on water samples collected throughout the drinking water system were
performed by accredited, licensed laboratories. These tests include both regulatory and
operational testing – in most cases only regulatory reporting is included in this report. In all
cases, the drinking water supplied to all customers was confirmed safe and the water was of
higher quality than all Ontario and Canadian health-related guidelines.
The Guelph Drinking Water System is defined as a large residential system operated under
the regulatory requirements of the Safe Drinking Water Act and the Ontario Water
Resources Act (accessed at Ontario e-laws). In 2019, the Guelph Drinking Water System
operated under Municipal Drinking Water Licence (MDWL) 017-101, Issue numbers 11 and
12 and the Drinking Water Works Permit (DWWP) 017-201, Issue numbers 7 and 8.
The MDWL and the DWWP describe system-specific requirements that are supplementary to
provincial regulations and act as licences for water supply and distribution operations. These
documents outline specific conditions and requirements regarding operation, maintenance
and upgrades that are required by the system and are considered regulatory in nature.
These documents are available by request for viewing at Water Services, 29 Waterworks
Place, Guelph.

Water Services’ Annual and Summary Report
a) Incidents of Regulatory Non-Compliance
This section describes all incidents of non-compliance.
Guelph Drinking Water System
There were four incidents of non-compliance associated with the Guelph Drinking Water
System in 2019. The four incidents are described below:
• Caps on the water level monitoring access points on two wells, located inside secure
buildings, were found to not be in place. This was immediately corrected at the time
of inspection.
• A Form 1 (Record of Watermains Authorized as a Future Alteration) was completed in
November 2019 for work on a watermain that occurred in September 2019. The City’s
DWWP requires the Form 1 to be completed prior to the watermain being placed into
service. Water Services is working with Engineering and Transportation Services to
develop a procedure to ensure that Form 1’s are completed prior to any watermain
additions, modification, replacement or extension being placed into service.
• A chlorine residual in a dead-end of the distribution system was found to be below
0.05mg/L, which is discussed further in section b) Adverse Water Quality Incidents.
Water Services is committed to ensuring that an acceptable chlorine residual is
maintained throughout the water distribution system and has implemented a regular
flushing program in this area.
• It was found that HPC analysis was not completed on two treated water samples
taken on February 6, 2019. This was caused by human error, where the treated water
samples were mistakenly recorded on the chain of custody as raw water samples;
HPC analysis is not required for raw samples. Water Services now has separate chains
of custody for raw and treated water samples to help eliminate the chance of this
reoccurring.
A score of 89.42% was achieved in the 2018-2019 Ministry of the Environment,
Conservation and Parks Annual Inspection Report for the Guelph Drinking Water System.
Water Services has corrected all issues of non-compliance identified during the MECP
inspection. Through the root-cause analysis process, Water Services initiates continual
improvement measures and implements new policies and procedures to prevent issues of
non-compliance from re-occurring.
2019 Annual and Summary Report
Page 10 of 182
Gazer Mooney Subdivision Distribution System
There were no incidents of non-compliance associated with the Gazer Mooney Subdivision
Distribution System in 2019.
A score of 100% was achieved in the 2018-2019 Ministry of the Environment, Conservation
and Parks Annual Inspection Report for the Gazer Mooney Subdivision Distribution System.
b) Adverse Water Quality Incidents
This section describes all Adverse Water Quality Incidents (AWQI’s). This term refers to any
unusual test result from treated water that does not meet a provincial water quality
standard, or a situation where disinfection of the water may be compromised. An adverse
water quality incident indicates that on at least one occasion and at a certain instance in
time, a water quality standard was not met. On average, the Guelph Drinking Water System
processes four to five AWQI’s annually.
Many AWQI’s have proven to be the result of water sampling and testing problems rather
than poor water quality. False positive results can be caused by: contaminated sampling
containers and equipment; improper sampling technique; handling and transportation; and
sampling analysis errors.
Please note: The City was granted regulatory relief from Schedule 15.1 of O. Reg. 170/03 in
favour of a Guelph specific Lead Reduction Plan (LRP). Residential sample results collected
under the LRP that have lead concentrations above 10 µg/L, are tracked and reported to
Wellington-Dufferin-Guelph Public Health, the Ministry of the Environment, Conservation and
Parks (as per MDWL 017-101, Schedule D) and the customer. See 0 Status of Ongoing and
Emerging Water Quality, Supply and Distribution Initiatives for more information on the
Lead Reduction Plan.
Guelph Drinking Water System
In 2019, there were three adverse water quality incidents (AWQI’s #144857, #144859 and
#148104) and a summary of these are included in Table 1.

2019 Annual and Summary Report
Page 14 of 182
c) Deviations from Critical Control Point (CCP) Limits
and Response Actions
A critical control point in the drinking water system is where control can be applied to
prevent or eliminate a drinking water hazard, or to reduce it to an acceptable level. Water
Services has identified three Critical Control Points (CCP) in the drinking water system:
1) Multi-Barrier Primary Disinfection - To remove or inactivate pathogens potentially
present in the source water.
2) Secondary Disinfection - To ensure the maintenance of a disinfectant residual
throughout the distribution system.
3) Backflow Prevention - To prevent cross-contamination that can result from the flowing
back of or reversal of the normal direction of flow of water.
Any deviations from the CCPs are reported to both the Owners and Top Management, and
are summarized in b) Adverse Water Quality Incidents in this report. There was one
deviation from the Critical Control Points in 2019. The deviation was related to secondary
disinfection. Information about this incident and actions taken to resolve the issue is
outlined in b) Adverse Water Quality Incidents under item 3.
Additional information (e.g. critical control limits and response actions) is included in
Appendix A: Summary of Critical Control Points and Critical Control Limits.
d) The Effectiveness of the Risk Assessment Process
This section confirms the occurrence of reviews of the risk assessment process. The risk
assessment process determines the effectiveness of identifying and appropriately assessing
the risk of hazards and hazardous events to the drinking water system. It also identifies the
appropriate control measures; critical control points (CCPs); and related critical control
limits (CCLs) related to the hazards and hazardous events. A description of the CCPs and
CCLs are included in Appendix A: Summary of Critical Control Points and Critical Control
Limits.
The annual risk assessment review was conducted by Water Services staff over several
meetings between August 15 and August 30, 2019. The updated risk assessment outcomes
was subsequently reviewed and approved at a management meeting on September 24,
2019. The results of the Risk Assessment are not made available to the public, but are made
available to internal staff and the Guelph DWS Owners.
2019 Annual and Summary Report
Page 15 of 182
Through the risk assessment process, the following Water Services program or process
aspects were added:
• Locates - Inability to properly locate due to no tracer wire installed or installed
incorrectly or not locatable material leading to watermain damage;
• Locates - Inability to properly locate due to inaccessible, incorrect or not updated
records resulting in damaged watermain.
e) Internal and Third-Party Audit Results
Internal auditing and third-party auditing is performed to fulfill the mandatory requirements
of the Drinking Water Quality Management Standard (DWQMS). The internal audit is
completed using trained internal Water Services staff as auditors. The purpose of audits are
to evaluate the level of conformance of Water Services to the DWQMS. Audits identify both
conformance and non-conformance with the Standard, as well as, opportunities for
improvement. Appendix B: Summary of Internal and External Audit Plans includes the past
two years’ internal and external audit plans and the plan for the upcoming year.
2019 Internal Audit
The internal audit was completed on April 1 to April 5, 2019 and looked at 17 processes at
Water Services. Many strengths were identified during the internal audit, including a sense
of pride, ownership and commitment to the DWQMS and processes outlined in the
Operational Plan. Participating staff at all levels are knowledgeable and aware of their duties
as it relates to providing safe drinking water to the water consumers.
There were no non-conformities identified during these internal audits.
Various opportunities for improvement, such as: improved document and records control;
training; communications; essential services; staffing levels; emergency management; and
standard operating procedure creation were also noted in the internal audit report. Water
Services strives to promptly address issues identified in internal audits as part of continuous
improvement of its procedures and processes. The next internal audit is scheduled to take
place between March 2 and 6, 2020.
2019 External Audit
The third-party external on-site verification audit was completed between November 25 and
November 27, 2019 by NSF International Strategic Registrations and looked at 24 processes
at Water Services. Accreditation to the DWQMS Version 2.0 was maintained.
2019 Annual and Summary Report
Page 16 of 182
The auditor noted that there continues to be strong evidence of ongoing commitment to the
DWQMS at the City of Guelph. System strengths observed during the audit include:
• Staff participation / engagement
• Ownership / pride
• DWQMS documentation
• Management review process
• Internal audit process
• Continual improvement
• Communication: internal and external
• Risk assessment process
• Leak detection program
• Emergency planning / testing processes
There were two minor non-conformities identified during this audit. The first minor non-
conformance related to Document and Records Control (DWQMS Element 5). The auditor
noted that: there was a standard operating procedure that does not reflect current practices
for calibration and verification of colorimeters; and an obsolete version of design
specifications was found to be available to operators.
The second minor non-conformance relates to Essential Supplies and Services (DWQMS
Element 13) and documentation around chemical receiving. Instances were identified where
the lot number was missing on the bill of lading from our chemical supplier.
In both minor non-conformances, immediate containment of the issues were taken. A root-
cause-analysis was completed to identify corrective and preventative actions to ensure that
the issues will not occur again. In both minor non-conformances, the auditor accepted our
corrective and preventative actions and the minor non-conformances are considered closed.
Noted opportunities for improvement by the auditor were related to improving the following
processes:
• Document and Records Control (DWQMS 5);
• Communications (DWQMS 12);
• Infrastructure Maintenance, Rehabilitation and Renewal (DWQMS 15);
• Sampling, Testing and Monitoring (DWQMS 16); and
• Continual Improvement (DWQMS 21).
Water Services maintains a culture of continual improvement and works towards
implementing improvements suggested by the external auditor. The minor non-
2019 Annual and Summary Report
Page 17 of 182
conformances and opportunities for improvement will be reviewed by the external auditor at
the next on-site audit, scheduled between November 23 and 25, 2020.
f) Results of Emergency Response Testing
Emergency response testing is regularly completed as part of the Water Services’ Quality
Management System (QMS) to ensure that Water Services maintains a reasonable readiness
to deal with emergencies and abnormal events. The ability to properly manage emergencies
and unplanned failures is critical in demonstrating that Water Services has taken a diligent
approach in its operations.
Water Services’ last emergency test exercise involved a mock scenario where a large
watermain break occurred on a section of 20 inch watermain that feeds the west end of the
city, which resulted in low pressure and/or no water for the affected customers, a boil water
advisory and a workplace incident where a car drove into the watermain trench, resulting in
an investigation by the Ministry of Labour. The emergency test exercise was held on
November 1, 2019 and included representatives from the Ministry of the Environment,
Conservation and Parks (Inspector), representatives from Wellington-Dufferin-Guelph Public
Health (WDGPH) as well as Water Services and other City staff. All other Water Services’
staff participated in sessions that took place between November 6 and 8, 2019.
Water Services had three actual emergency events in 2019.
The first one occurred on May 10, 2019. A contractor who was working on site at Water
Services punctured the gas main with a backhoe. Water Services staff evacuated the
building until the gas supply could be shut off. Fire Services were on scene to assess the
situation and determine when staff could return to work. The gas main was repaired by
Union Gas.
The second emergency involved four watermain breaks on a section of Silvercreek Parkway
on the weekend of September 13, 2019. Based on the poor structural condition of this
segment of watermain, an emergency replacement of that section of pipe was initiated on
September 16, 2019. Following completion of reconstruction of this segment of pipe it was
returned to regular service in early October.
The third emergency involved a large watermain break on a 16” watermain on Speedvale
Avenue between the Hanlon Parkway and Silvercreek Parkway on November 30, 2019. This
resulted in significant water loss from the Speedvale Tower; although pressure was
maintained throughout the north end of the city during the watermain break. Emergency
repairs were completed by a contractor, with Water Services staff overseeing the repairs.
2019 Annual and Summary Report
Page 18 of 182
Feedback from emergency testing and from actual emergency events is gathered during
debriefing sessions and improvement items are incorporated into the Emergency Plan,
standard operating procedures and/or daily operations.
Table 3 includes the dates of Completed Emergency Response Tests for the past three years

g) Operational Performance and Statistics
The following section describes Operational performance statistics within Water Services
that includes:
• 2019 Totalized Pumpages as per the Municipal Drinking Water Licence and Permits to
Take Water;
• 2019 Instantaneous Flows as per Permit to Take Water requirements;
• Water Production and Population;
• 2019 Arkell Springs Glen Collector Flows;
• Water Supply Capacity;
• System Maintenance and Updates; and
• Status of Ongoing and Emerging Water Quality, Supply and Distribution Incentives.
2019 Totalized Pumpages and Instantaneous Flows
2019 Annual and Summary Report
Page 20 of 182
The Safe Drinking Water Act and the Ontario Water Resources Act each require that
operating authorities record and report both water takings as governed by Permits-to-Take-
Water, and water being supplied to the City of Guelph.
Summaries of total water pumped, instantaneous flows and capacity (flows and volumes
compared to rated capacities) by the City of Guelph can be found in Appendix C: Total
Water Pumped and Instantaneous Flows.
Figure 3 below, depicts the water pumpage rate in cubic metres per day (m3/day) that is
averaged each week.
Figure 3: Totalized Pumpages, 2019
Water Services processed 17,160,654 cubic metres (17.2 billion litres) of water to the
distribution system in 2019, equivalent to 6,864 Olympic-sized swimming pools. This
represents 0.9 per cent less water being supplied to the distribution system in 2019 as
compared to the same time period in 2018 and 1.4 per cent more water than in 2017.
2019 Annual and Summary Report
Page 21 of 182
The average daily water demand was 47,015 cubic metres (47.0 million litres). The
maximum day production of water in 2019 was 58,411 cubic metres (58.4 million litres) and
occurred on November 30, 2019. The minimum day production of water in the same time
period was 32,477 cubic metres (32.5 million litres) and occurred on December 26, 2019.
Water Production, Consumption and Population
Figure 4 below shows the City of Guelph’s annual average daily water production, annual
average daily consumption, annual peak day demand, and population from 2009 to 2018.
Consumption data for 2019 was not available at the time of publication.
During this time, the City of Guelph’s population increased 12 per cent while at the same
time annual average daily water production and consumption demonstrate a downward
trend (3 per cent) based on linear regression.
Fluctuation in water production and consumption is anticipated to occur, year to year, based
on a number of factors, including seasonal temperatures and annual precipitation, system
demands (including planned and unplanned maintenance) and steady population growth.
2019 Annual and Summary Report

Figure 4: Guelph Water Production, Water Consumption, Population
Arkell Springs Glen Collector System Source Water
The Arkell Springs Glen Collector System (Collectors), one of Guelph’s many water sources,
consists of a gravity-fed, under-drain system that collects shallow overburden groundwater.
This system has been in use since the early 1900’s and can represent as much as 40 per
cent of the total city-wide daily water production when in operation. When the output of this
source is reduced, Water Services is required to make up the difference from other water
supplies. Throughout the year, the production from this water supply varies from an
approximate low of 4,000 cubic metres (4 million litres) up to an approximate high of
20,000 cubic metres (20 million litres) per day.
Seasonally, between April 15 and November 15, the City has a Permit-to-Take-Water that
allows water to be pumped from the Eramosa River to a pond and trench-based Recharge
System. In the Recharge System, the river water enters the trench where it filters through
the ground and is later captured in the Arkell Springs Glen Collector System.
2019 Annual and Summary Report
Page 23 of 182
In 2016, the Recharge System was out of service to accommodate infrastructure
improvements including an extension of the trench system in an effort to capture more
water in the Collectors. The Recharge System was returned to service in May 2017 and
tested during 2017 and 2018 to determine the impact of the extended trench on the
Collector flows. In 2018, 1,368,766 m3 of raw water was pumped from the Eramosa River
(from April through November) and 1,119,787 m3 of raw water was pumped from Arkell
Well 7 (from March through September) to the Recharge System as part of a Collector
System capacity test. Recent modelling showed that approximately 52 per cent of this
volume was captured in the Collector system.
The productivity of the Collectors can be used as one of many predictive tools. If the
production volume from the Collectors is low, then it can be assumed that other water
supplies would be needed to make up the difference. This may alter how regular
maintenance is performed as well as the urgency with which repairs are made to supplies
that unexpectedly go off-line as they may be needed to supplement overall production for
the City when the Collector System is unable to produce a sufficient supply.
The Collectors have produced 3,853,004 cubic metres (3.9 billion litres) of water in 2019,
which is approximately 22 per cent of Guelph’s total water production. This represents 4.2
per cent less water as compared to the same time period in 2018 and 1.4 per cent more
water than in 2017.
For a visual representation, please refer to Figure 5, which depicts the Arkell Spring Grounds
Collector flow volumes in cubic metres per day (m3/day) that is averaged each week.

Please note: Arkell Well 7 contributed 1,119,787 m3 to the Recharge System (from March
through September 2018) with approximately half (560,000 m3) captured in the Collector
flow post filtration through the ground.
Water Supply Capacity
Pumping stations are typically rated on their firm capacity, which is defined by the Ministry
of Environment, Conservation and Parks (MECP) Design Guidelines for the Design of
Drinking Water Distribution Systems (2008) by the following criteria:
• Capacity of the pumping station with the largest unit out of service if the station
supplies a pressure zone with adequate storage available for fire protection and
balancing;
• Capacity of the pumping station with the two largest units out of service if the
pumping station serves a pressure zone that does not have adequate floating storage
available and is the sole source of supply in the area.
2019 Annual and Summary Report
Page 25 of 182
This approach however, does not address the “system” firm capacity. Neither is it directly
applicable to a groundwater system with many sources. Firm Capacity assessment of a
water supply system is essentially an exercise in risk assessment, such that a municipality
will incorporate measures or strategies to minimize the risk of certain aspects of the system
being off-line, and will accept a level of risk that a portion of the system will not be available
due to maintenance, water quality issues or other.
A proposed approach to more accurately reflect system conditions for the City considers
equipment reliability (i.e. assumptions for percentage of inoperable wells or pumps) and
also potential future contamination issues. This will also take into consideration wells that
are presently shut down for water quality reasons and whether it would be acceptable to
bring these sources back online in emergency conditions.
Historically, City staff have assessed a safe, sustainable yield of existing groundwater
supplies through hydrogeological assessments conducted mainly through quadrant studies,
subsequent pumping tests and operational data. The groundwater flow model has also been
used to confirm sustainable capacity, however both of these methods reflect permitted
capacities, either takings allowed in the Permit to Take Water (PTTW) or those included in
Environmental Certificates of Approval (ECA) for each well or pumping station.
In order to more accurately address the questions of system firm capacity, Water Services
staff annually review the operational water demand data for water supply facilities under
maximum demands. Values used for permitted pumping rate and firm capacity calculations
by well are provided in Table 4. The permitted pumping rate is the rate of pumping allowed
as identified in the Permits to Take Water. The firm capacity rate is the actual rate of
pumping that can be achieved at each well.

10 The firm capacity rate is the actual rate of pumping that can be achieved at each well. 11 The Arkell Springs Wellfield consists of five (5) municipal drinking water production wells:
Arkell 6, Arkell 7, Arkell 8, Arkell 14 and Arkell 15. All of the aforementioned Arkell Wells are
contained within the same Permit to Take Water (No. 5061-9ZKKWV). Notwithstanding the
specified maximum permitted taken per day, any combination of these wells can be used to
obtain the permitted rate.
2019 Annual and Summary Report
Page 27 of 182
Water Services staff use the calculated firm capacity values in order to aid planning of
scheduled shutdowns and maintenance of the water supply wells. Staff hold monthly
meetings to review project statuses that affect firm capacity. At the meetings there are
discussions related to the progress of maintenance and upgrade operations. The purpose of
the monthly meeting is to ensure adequate servicing capacity is available to meet the City’s
water demands while maintenance and capital upgrades are undertaken to maintain the
system in a fit state of repair.

SCADA System Improvements
The Supervisory Control and Data Acquisitions (SCADA) system is the computerized control
system that monitors and automatically controls the pumps, valves, water towers and online
instrumentation at the 25 water facilities located throughout the City and 8 water facilities
located in the Arkell Springs well field. SCADA also monitors 49 flowmeters and pressure
transmitters located throughout the water distribution system.
2019 Annual and Summary Report
Page 30 of 182
The SCADA system performs the vital role of monitoring/logging process data to ensure
regulatory compliance, and providing tools to the Operations team that enables them to run
the City’s water system in a consistent manner. Furthermore, the SCADA system is also
configured to automatically shut down facilities and/or notify an on-call operator in the case
of abnormal process conditions. The SCADA system also monitors the security systems at
all water facilities. Lastly, the SCADA system also provides process data reports and queries
that are used for compliance reporting, hydraulic system modelling, and long term planning.
In 2019, SCADA system uptime was over 99.995 per cent, due to SCADA network upgrades
that were undertaken in 2017 to add redundant auto-failover backup SCADA network links
to all facilities and due to SCADA backup system upgrades in 2018-2019.
Upgrades to the SCADA system in 2019 were focused around updating SCADA system
programming standards, modernizing control system programming, and updating backup
systems. In addition to incremental updates, all-new SCADA code and screens were
deployed at 2 facilities in conjunction with capital projects.

Water Distribution Locates
In 2014, The City of Guelph registered its utility infrastructure with ON1Call, as mandated
by the Ontario Underground Infrastructure Notification System Act, 2012.
Since registering, the City experienced a significant increase in locate request volumes. This
increase in volume ensures that Water Services is notified of and attends all locate requests
for every excavation in proximity to water infrastructure. This prevents damage to City
infrastructure and protects the City’s water quality and quantity.
In order to provide efficient locate services across the corporation, the City has transitioned
all infrastructure locates into one corporate group which is housed at Water Services. This
includes water, sanitary and storm sewers, traffic signals, and fibre optics. Utility locators
now locate all infrastructure in one site visit rather than each department individually. Table
9 includes all water locate requests received and responded to in 2019 with a year to year
comparison below in Table 10.

This includes summaries and updates related to the implementation of the:
• 2016 Water Efficiency Strategy;
• Arkell Springs Forest Stewardship Project,
• Source Water Protection Plan;
• Lead Reduction Plan; and
• Frozen Services Monitoring Program.
Water Efficiency Strategy
The City of Guelph strives to be a leader in water conservation and efficiency. As one of
Canada’s largest communities reliant on a finite groundwater source for drinking water
supply, the City’s ability to reclaim water and wastewater serving capacity through
conservation and efficiency initiatives offers numerous benefits to our community and local
ecosystem. Water Services continues to promote the ongoing sustainability of our finite
water resources through active water conservation and efficiency programming to meet the
water reduction targets as outlined in the 2014 Water Supply Master Plan.
Appendix I: Water Efficiency Program – 2019 Annual Progress Report presents the
achievements and progress made for the period of January 1 to December 31, 2019 in the
implementation of the 2016 Water Efficiency Strategy.
2019 Annual and Summary Report
Page 34 of 182
Source Water Protection Plan
The City of Guelph is committed to drinking water source protection and in 2016, Council
appointed risk management staff to implement the Source Water Protection program.
The City of Guelph falls under the Grand River Source Protection Plan, which was approved
by the MECP and became effective on July 1, 2016. Of the 72 policies identified in the Grand
River Source Protection Plan, the City of Guelph is the primary implementing body for 48 of
the 72 policies, with the remaining policies to be implemented by provincial ministries. As of
December 31, 2019, 28 of the 48 policies have been fully implemented, based on priority
basis or deadline.
Appendix K: Source Water Protection includes a highlight of the progress made for the
period of January 1 to December 31, 2019 in the implementation of the City of Guelph’s
Source Water Protection program. This third annual report summarizes information
requested from the Risk Management Official by the Source Protection Authorities, as
required under Section 81 of the Clean Water Act, 2006 (CWA).
For more information on Guelph’s Source Water Protection Program, visit
guelph.ca/sourcewater.
Arkell Springs Forest Stewardship Project
The Arkell Spring Grounds cover an area of 804 acres. The area is comprised of old and new
forested areas. The objective of the Arkell Springs Forest Stewardship Project has been to
protect the drinking water source supply by monitoring general forest health, managing tree
plantings and enhancing fallow areas with new plantings.
Managed forest stands require continued maintenance and observation to ensure the health
of the forest and prevent any unnecessary losses. The many benefits of this long-standing
Stewardship Project include:
• the creation and maintenance of a diverse and functioning forest cover;
• maintenance and re-generation of older forested areas on the property;
• protection and recharge of underground aquifers which supply the City’s water;
• prevention of undesirable surface water runoff and flooding into local waterways;
• localized temperature stabilization;
• retain precipitation to enhance infiltration and improve supply; and
• regulating water flow.
2019 Annual and Summary Report
Page 35 of 182
This property management approach results in the highest possible quality of water to
supply Guelph’s drinking water system.
To improve the overall health of the property, a tree planting program for fallow farm fields
has been ongoing since 2007. On a volunteer basis, the Community Environmental
Leadership Program (CELP) with the Upper Grand District School Board has planted 28,500
trees on 18 acres, and Bartram Woodlands (on-site contractor) has planted 39,240 trees on
another 16 acres.
In 2019, a five-year plan for forest management was developed to identify priorities at the
Arkell Spring Grounds. The plan identifies tree planting, maintenance and invasive
vegetation removal to ensure the health of this site. It further recommends a forest
inventory plan to guide the management of this important source protection measure.
Arkell Springs Forest Stewardship Project is an important part of the Arkell and Carter
Integrated Property Management Plan.
Lead Reduction Plan
The City has been working proactively to address the presence of lead service lines (LSLs) in
Guelph since 2007 through identification and replacement of both the private and public
portions of LSLs. Full LSL replacement has demonstrated to be effective in reducing lead
concentrations and achieving regulatory compliance as measured at the point to water
consumption.
The City of Guelph’s Lead Reduction Plan (LRP) was developed in lieu of a Corrosion Control
Plan (as outlined in Ontario Regulation 170/03 Schedule 15.1) and was formally approved
by the MECP on March 21, 2012. The LRP focuses on physical lead service line replacement
through verification sampling, financial incentives and public outreach.
As per the City of Guelph MDWL 017-101 - Schedule D, the City is required to submit all
lead sampling data every 6 months and an annual Evaluation Report to assess the
effectiveness of the Lead Reduction Plan.

Lead Sampling
Over 5,000 homes/businesses have been sampled for lead to identify the presence of LSLs
and to monitor lead levels following a LSL replacement. For the period of January 1 to
December 31, 2019, 90 private plumbing locations were sampled for the purposes of
verifying the presence of a LSL. Of these locations, 11 locations were above 0.005 mg/L
indicating presence of a lead service line and 4 also exceeded the ODWQS of 0.01 mg/L.
15 Includes all samples as required by the MDWL or Lead Reduction Plan.
2019 Annual and Summary Report
Page 37 of 182
Lead samples are collected before and after a LSL replacement has been undertaken. There
were 5 locations resampled in order to monitor lead levels post-replacement. Based on
sample results to date, regulatory compliance is expected at individual sites that have
undergone a full LSL replacement or where there is no lead remaining in the service line.
Lead Service Line Replacements
Since 2007, there has been a total of 703 lead service lines replaced in the City. As a result,
91 per cent of these homes are now considered to be ‘lead-free’ service lines (i.e. either a
full replacement or a partial replacement that connected to a non-lead material). There were
14 LSL replacements undertaken in the City between January 1 to December 31, 2019. Of
these, there were 3 LSL replacements on City property and 2 LSLs were replaced on both
City and private property by coordinating the work with the homeowner. An additional 9 LSL
replacements were completed on private property by the homeowner.
Since 2010, the City initiated financial incentive programs to encourage replacement of
privately-owned LSL by reducing the financial burden to property owners. The grants cover,
on average, 75 per cent of the LSL replacement cost for homeowners. From 2010 to Dec.
31, 2019, 229 privately owned lead service lines were replaced through the grant program,
as presented in Table 13.

Targeted outreach regarding the Grant Programs is directed at all properties with known or
suspected privately-owned LSLs. The main barriers to privately owned LSL replacement for
homeowners include financial costs, disruption to property, rental properties and people who
are unconcerned about the health risks of lead in drinking water. Direct communications
continued to be been tailored to address these barriers.
Frozen Water Pipe Prevention and Monitoring Program
Water Services takes a proactive approach in monitoring and preventing frozen water pipes.
The purpose of the 2015 Council-approved Frozen Water Pipe Policy is to prevent and
manage interruptions to the City’s supply of water, caused by the temporary freezing of City
and/or customer water pipes, so that customers maintain reliable, continuous access to
water.
Water Services monitors daily temperatures, frost levels, degree-days and water
temperature in the water distribution system. When certain thresholds are reached, the
freeze prevention program is initiated.
2019 Annual and Summary Report
Page 39 of 182
The Frozen Water Pipe Program requires customers to take specific actions to prevent the
freezing of water pipes. Water Services has identified two tiers for their frozen water pipe
prevention program. Tier 1 properties are most susceptible to freezing and have historically
frozen every year or are properties where running water will ensure the water mains in the
area do not freeze. Tier 2 properties are also at risk for freezing and have had frozen pipes
in the past during prolonged periods of severe winter temperatures. Through communication
with these customers, Water Services works hard to ensure that frozen water pipes are
prevented. The customers in both of these Tiers are registered in our notification program.
For more information on the Frozen Water Pipe Program, visit guelph.ca/frozenpipes.
2019 Frozen Water Pipe Program Statistics
Through the winter of 2018/2019 Guelph experienced fluctuating temperatures throughout
the early part of the winter (November and December). Early into 2019, nighttime
temperatures consistently remained below -10°C, dropping below -20°C and remaining
steady for over a week. The result of which pushed frost down into the ground creating a
scenario with high probability of frozen water pipes.
By late January, 3.5 feet of frost was noted in the ground – the lowest frost depth for the
season. With the addition in the cumulative mean daily temperature (i.e. the lower the
temperature, the quicker the approach to the cumulative temperature trigger) it was
decided to initiate the freeze prevention program.
On January 21, Tier 1 and Tier 2 customers began running water as per the actions set out
in this program to prevent water pipes from freezing. As temperatures warmed up in
February, the frost level in the ground rose and forecasted temperatures saw no return to
cooler temperatures. By late February, all customers were contacted to cease running their
water, as per the program.
Summary of 2018/2019 Winter Statistics
• Temperature hit cumulative low trigger amount of -400°C: February 19.
• Lowest temperature recorded for the season was on February 1: -25.58°C.
• Lowest frost depth recorded for the season was 3.5 feet was on January 29.
• No frozen calls were received during the season.

Guelph Drinking Water System
This section describes the water quality monitoring, both regulatory and operational, that
has been completed in 2019.
Water Quality Review – Guelph Drinking Water System
Under the Safe Drinking Water Act, municipalities are required to monitor both the raw and
treated quality of the source water supplied. This monitoring is performed for both
regulatory compliance and due diligence and is expected to identify any changes within the
treated water, as well as, in raw source waters.
A note about all tables included in this section
1. All regulated chemicals detected in the City of Guelph’s treated water sources that are
above the lab’s MDL (minimum detection limit) are underlined indicating a hyperlink
to an Excel Workbook in Guelph’s electronic document management system (EDMS).
The workbook contains a definition of the parameter and an Excel worksheet for each
treated source where the parameter has been detected with values for all sample
results from January 1, 2007 to December 31, 2019. This database is used to closely
track the instances of the identified chemical parameters and therefore provide time
for planning and budgeting if treatment or an alternative supply is eventually required
due to the presence of a given parameter. The database is updated annually.
2. Tabulated data is from the best available information at the time of table creation.
3. If sampling for a particular schedule’s parameters (e.g. Schedule 23 and 24) did not
occur within the calendar year of the report, then the most recent values are included
in the report for reference.

Treated Water Quality Statistics – Guelph Drinking Water
System
O. Reg. 170/03 Schedule 6-5 - Continuous Monitoring Results
Summary
Water Services utilizes over forty regulatory and operational continuous monitoring devices
to measure water quality. Each regulatory device has controls associated with it such that in
the event that the device detects that a measured value is outside the acceptable
parameters for that location, the device causes an alarm to be sent to an Operator for
immediate response (24 hours per day, seven days per week) and either automatically
shuts down the station or activates a second alarm for immediate Operator response.
Both the minimum allowable levels (if applicable) and the target values for Water Services
regulatory continuous monitoring devices are listed in Table 19. The target values represent
a safety margin to ensure that regulatory requirements are satisfied at all times. Please note
that, continuous monitoring values all fell within acceptable regulatory standards in 2019.

O. Reg. 170/03 Schedule 13-6 and 13-7, “Three Month” Sampling
Results Summary
In 2019, all operational Treated Sources were sampled and analyzed for Schedule 13-6, 13-
16.1 and 13-7 parameters as per O. Reg. 170/03.
Regulation 170/03, Schedule 13-6 requires a minimum of one distribution sample taken
from the Distribution System where THM’s (trihalomethanes) are most likely to develop
(locations with high retention times). Water Services uses the Speedvale, Clair and Verney
Elevated Tanks for this purpose in the Guelph Drinking Water System. The Maximum
Allowable Concentration (MAC) for THM’s is 0.1 mg/L. However, for this parameter, the MAC
uses a running annual average of quarterly samples.
The results of the running annual average value for THMs for all related Distribution System
samples in each quarter of 2019 (Jan. 01 to Dec. 31) is below the half of the maximum
allowable concentration (½ MAC): Q1 = 0.023 mg/L; Q2 = 0.028 mg/L; Q3 = 0.034 mg/L
and Q4 = 0.039 mg/L.
Regulation 170/03, Schedule 13-6.1 requires a minimum of one distribution sample taken
from the Distribution System where HAAs (haloacetic acids) are most likely to develop.
Water Services uses Woods Sample Station, Ptarmigan Sample Station, Clair Tower Sample
Tap and Edinburgh South Sample Station for this purpose in the Guelph Drinking Water
System. The Maximum Allowable Concentration (MAC) for HAAs is 0.08 mg/L. However, for
this parameter, the MAC uses a running annual average of quarterly samples.
2019 Annual and Summary Report
Page 46 of 182
The results of the running annual average value for HAAs for all related Distribution System
samples in each quarter of 2019 (Jan. 01 to Dec. 31) is below the half of the maximum
allowable concentration (½ MAC): Q1 = 0.024 mg/L; Q2 = 0.021 mg/L; Q3 = 0.027 mg/L
and Q4 = 0.025 mg/L.
All operational Treated Sources were sampled and analyzed for Nitrates and Nitrites as per
Regulation 170/03, Schedule 13-7. There was no instance of an adverse result in 2019. Raw
sampling results are also presented in Table 20.

O. Reg. 170/03 Schedule 23 Results Summary
In 2019, all operational treated sources were sampled and analyzed for Schedule 23
parameters as per O. Reg. 170/03. All of the City of Guelph’s treated ground water sources
are on a three year sampling schedule. F.M. Woods’ Station is the exception and is sampled
on the annual surface water schedule due to the fact that five of the nine sources that
supply F.M. Woods are GUDI-WEF sources (the Carter Well 1 and 2, Arkell 1, Arkell 15 and
the Arkell Springs Glen Collectors).
The results of the Schedule 23 inorganic parameter analysis in 2019 were all under half of
the maximum allowable concentration (½ MAC) and the majority were under the
laboratory’s MDL (minimum detection level). Please refer to the section titled “O. Reg.
170/03 Schedule 23 Results Summary” included in Appendix D: Treated Water Quality
Statistics for more information.

O. Reg. 170/03 Schedule 24 Results Summary
In 2019, all operational Treated Sources were sampled and analyzed for Schedule 24
parameters as per O. Reg. 170/03. All of the City of Guelph’s treated ground water sources
are on a three year sampling schedule. F.M. Woods’ Station is the exception and is sampled
on the annual surface water schedule due to the fact that five of the nine sources that
supply F.M. Woods’ are GUDI-WEF sources (the Carter Well field, Arkell 1, Arkell 14 and the
Arkell Springs Glen Collectors).
The results of the Schedule 24 organic parameter analysis in 2019 were all under half of the
maximum allowable concentration (½ MAC) and the majority were under the laboratory’s
MDL (minimum detection level). Please refer to the section entitled “O. Reg. 170/03
Schedule 24 Results Summary” included in Appendix D: Treated Water Quality Statistics for
more information.
It should be noted that, before 2012, values for TCE (trichloroethylene) at Membro and
Emma occasionally crested the ½ MAC value of 0.0025 mg/L and as a result Water Services
moved to an “Increased Frequency Sampling Plan” as required by Regulation 170/03 - 13-5
which requires that sampling for this parameter be sampled every “three months” until two
consecutive sample results are below the ½ MAC value. As a precautionary measure, Water
Services samples on a monthly schedule at Membro and Emma wells. All other sources, are
sampled annually (minimally) for VOC’s (Volatile Organic Carbons) through a “Guelph VOC
Scan” in order to better track parameters such as TCE via more data. Currently, TCE is
above the MDL but below the ½ MAC at Membro, Water Street, Emma and Park treated
water samples.

O. Reg. 170/03 Schedule 13-8 and 13-9, “Five Year” Sampling Results
Summary
In 2019, all operational Treated Sources were sampled and analyzed for the Schedule 13-9
Fluoride parameter as per O. Reg. 170/03. In 2019, Fluoride (naturally present and not
added as part of the treatment process) was detected at all treated sources; the analytical
results were all under the maximum allowable concentration (MAC). The values in Table 24
reflect the 2019, Schedule 13-9 sampling regime.
Sodium, however, is sampled on a more frequent basis (annually) than the Schedule 13-8
requirement due to the fact that at every treated source, sodium levels are above the lower
reportable limit of 20 mg/L.
The increased frequency of sampling provides more data in order to better establish sodium
value trends. Sodium results for 2019 can be referenced in Table 24. This data is provided
to Wellington-Dufferin-Guelph Public Health, as required.

22 The aesthetic objective for sodium in drinking water is 200 mg/L. The local Medical Officer of Health should be notified when
the sodium concentration exceeds 20 mg/L so that this information may be communicated to local physicians for their use with
patients on sodium restricted diets. 23 Where supplies contain naturally occurring fluoride at levels higher than 1.5 mg/L but less than 2.4 mg/L, the Ministry of
Health and Long Term Care recommends an approach through local boards of health to raise public and professional awareness
to control excessive exposure to fluoride from other sources.

Gazer Mooney Subdivision Distribution System
This section describes the regulatory water quality monitoring that has been collected in the
Gazer Mooney Subdivision Distribution System in 2019. For regulatory sampling schedules
that do not occur in 2019 related to the Gazer Mooney System, the most recent historical
data is listed.
Water Quality Review - Gazer Mooney Subdivision Distribution System
Under the Safe Drinking Water Act, municipalities are required to monitor both the raw and
treated quality of the source water supplied. This monitoring is performed for both
regulatory compliance and due diligence and is expected to identify any changes within the
treated water as well as in the raw source waters.
A note about all tables included in this section
1. All regulated chemical parameters where values above the lab’s MDL (minimum
detection limit) have been detected in the City of Guelph’s treated water sources are
underlined indicating a hyperlink to an Excel Workbook in Guelph’s EDMS. The
workbook contains a definition of the parameter, an Excel worksheet for each treated
source where the parameter has been detected with values for all sample results from
January 1, 2007 to December 31, 2019. This database is used to closely track the
instances of the identified chemical parameters and therefore provide time for
planning and budgeting if treatment or an alternative supply is eventually required
due to the presence of a given parameter. The database is updated quarterly.
2. Tabulated values are from best available information at the time of table creation.
While the values documented here satisfy the regulatory minimum regulatory
requirements, Water Services performs many additional operational tests not listed in
this report.
3. All acronyms and initialisms included in tables are described in Appendix L: Glossary.
4. Please note that some hyperlinks in the tables are linked to Guelph’s electronic
document management system (EDMS) which is available for internal City use only.

O. Reg. 170/03 Schedule 13-6, “Three Month” Sampling Results
Summary
In 2019, Gazer Mooney Subdivision Distribution System was sampled and analyzed for
Schedule 13-6 and 13-6.1 parameters as per O. Reg. 170/03. Regulation 170/03, Schedule
13-6 requires a minimum of one distribution sample taken from the Distribution System
where THMs (trihalomethanes) are most likely to develop (points with high retention times).
The MAC for THMs is 0.1 mg/L. However, for this parameter the MAC uses a running annual
average of quarterly samples. These results are presented in Table 28.
The results of the running annual average value for THMs in the Gazer Mooney Subdivision
Distribution System samples in 2019 were below the half maximum allowable concentration
(½ MAC): Q1 = 0.020 mg/L; Q2 = 0.018 mg/L; Q3 = 0.018 mg/L and Q4 = 0.019 mg/L.
Regulation 170/03, Schedule 13-6.1 requires a minimum of one distribution sample taken
from the Distribution System where HAAs (haloacetic acids) are most likely to develop. The
MAC for HAAs is 0.08 mg/L. However, for this parameter the MAC uses a running annual
average of quarterly samples.
The results of the running annual average value for HAAs in the Gazer Mooney Subdivision
Distribution System samples in 2019 is below the half maximum allowable concentration (½
MAC): Q1 = not detected; Q2 = not detected; Q3 = not detected and Q4 = not detected.

O. Reg. 170/03 Schedule 13-8 and 13-9, “Five Year” Sampling Results Summary
In 2019, Gazer Mooney Subdivision Distribution System was sampled and analyzed for the Schedule 13-9 Fluoride parameter as
per O. Reg. 170/03. In 2019, Fluoride (naturally present and not added as part of the treatment process) was detected; the
analytical result was under the maximum allowable concentration (MAC). The values in Table 29 reflect the 2019, Schedule 13-9
sampling regime.
Sodium, however, is sampled on a more frequent basis (annually) than the Schedule 13-8 requirement due to the fact that at
every treated source, sodium levels are above the lower reportable limit of 20 mg/L. The increased frequency of sampling
provides more data in order to better establish sodium value trends. Sodium results for 2019 can be referenced in Table 29. This
data is provided to Wellington-Dufferin-Guelph Public Health, as required.
24 This standard is expressed as a running annual average. 25 This standard is expressed as a running annual average.

General Chemistry Results Summary
In addition to the regulatory sampling and analysis required for the operation of the Gazer Mooney Subdivision, Water Services
samples for parameters as listed in Table 30 in order to gather additional data and answer common inquiries from the public.
26 The aesthetic objective for sodium in drinking water is 200 mg/L. The local Medical Officer of Health should be notified when
the sodium concentration exceeds 20 mg/L so that this information may be communicated to local physicians for their use with
patients on sodium restricted diets.
27 Where supplies contain naturally occurring fluoride at levels higher than 1.5 mg/L but less than 2.4 mg/L, the Ministry of
Health and Long Term Care recommends an approach through local boards of health to raise public and professional awareness to control excessive exposure to fluoride from other sources.

i) Follow-up on Action Items from Previous
Management Reviews
A Management Review meeting was held on January 25, 2019 and January 29, 2020. The
following is a summary of results of the management review. Appendix F: Action Items
from Management Review includes the action items from the meetings. Items 1-12 are from
the January 25, 2019 Management Review meeting and items 13-17 are from the January
30, 2020 Management Review Meeting.
Results of the Management Review, the identified deficiencies,
decisions and action items
The summary below includes identified deficiencies and decisions from the meeting held on
January 30, 2020.
Deficiencies
• There were four identified non-compliance issues identified in the 2018-2019 Ministry
of the Environment, Conservation and Parks inspection. Through the Root-Cause
Analysis program, Water Services has worked to implement policies and procedures
to reduce the likelihood of these non-compliances re-occurring in the future.
• Three AWQI’s occurred in 2019 in the Guelph Drinking Water System and one in the
Gazer Mooney Subdivision Distribution System. Three of the AWQIs were related to
sodium exceedances and one related to an incident where the chlorine residual in a
dead-end watermain was found to be below 0.05mg/L.
• There was one deviation from a Critical Control Point relating to the low distribution
system (secondary) chlorine residual found in a dead-end section of watermain.
Corrective and preventive actions have been taken to prevent this from re-occurring
in the future.
• There were two minor non-conformance issues identified in the 2019 accreditation
(external) audit. A corrective action plan was sent to the accreditation body and was
accepted on December 15, 2019.
Decisions
• See section d) The Effectiveness of the Risk Assessment Process regarding decisions
made in the Risk Assessment process on September 24, 2019.
• Investigate using J-Plugs on the drop tubes in the production wells.
• Consider adding water loss data to the Annual and Summary Report for 2020.
2019 Annual and Summary Report
Page 68 of 182
• Perform additional analysis on the frozen services program, specifically the running
tap program, and how it relates to water consumption and water production.
• Look at adding a line for performance testing to Table 6 for next year’s annual report.
• Have the SCADA group provide C3 Water with copies of facility P&ID, PFD and
equipment layout drawings so that the hydraulic model can be adjusted to take into
account pipe friction factors within treatment facilities.

Sentry Monitoring Wells
A consultant was retained in 2015 to develop a groundwater monitoring network in the area
of the Membro and Emma Production Wells. These particular wells were categorized as
having a drinking water quality issue for Trichloroethylene (TCE), a volatile organic
compound (VOC) under the Clean Water Act. The source(s) of the VOCs is (are) unknown
but there are potential sources in the vicinity of each well. The main objective of this project
was to review the potential contaminant sources and install monitoring wells (i.e. Sentry
Wells) between the potential VOC sources and the municipal wells that will be monitored
and used to document changes in groundwater quality. These wells can provide an early
warning of potential contamination moving toward the production well and also track
changes in existing groundwater quality.
As such, a sampling plan has been created to regularly collect water quality samples from
each of the eight (8) Sentry Wells, within their respective vertically discrete sampling
intervals. Review of the data collected thus far is ongoing and the retained consultant is
expected to deliver a final report on the status of this project in early 2020.
Carter Monitoring Program – Operational Testing
The Permit to Take Water for Carter Well 1 and 2 requires that the Carter Wells be operated
at increased levels in conjunction with monitoring in the Torrence Creek Subwatershed. This
monitoring was completed via consultant in 2019. The purpose of the monitoring is to
quantify impacts within this subwatershed.
Staff Certification
The following tables (Table 32, Table 33 and Table 34) describes all Operators and
Management staff with various classes of provincial Drinking Water Operator Certificates
and years’ experience, as of December 31, 2019. Due to the system reclassification in late
2018, there was an increase in Class I operators in 2019 to meet the new certification
requirements.

Changes Affecting the Quality Management System (QMS)
Ontario’s updated Drinking Water Quality Management Standard
(DWQMS) Version 2.0
Guelph Water Services implemented the requirements of the updated DWQMS Version 2.0,
released in February 2017, in its quality management system. Water Services was
accredited to DWQMS Version 2.0 in the 2018 external audit and maintained accreditation in
the 2019 audit.
Quality Management System Implementation
Guelph Water Services strives for continual improvement in all of its programs and
processes. Improvements made to the drinking water system and its process are evaluated
through: internal and external audits; staff suggestions; risk assessments; emergency
training and testing; consumer feedback and through the management review process.
Water Services at the City of Guelph is committed to providing consumers with a safe,
consistent supply of high quality drinking water while meeting or exceeding, and continually
improving on legal, operational and quality management system requirements.
Throughout 2020, we will continue with a proactive approach to the DWQMS by:
• Maintaining accreditation to the DWQMS 2.0;
• Identifying ways to improve the drinking water system and its related processes;
• Expanding knowledge and involvement of staff for collaboration and integration of the
quality management system;
• Ensuring that any deficiencies identified are responded to and corrected quickly and
efforts are taken to ensure that the problem does not reoccur;
• Collaborating with other municipalities to ensure that we are enhancing our
performance standards and operating practices; and
• Continuing advancements to emergency prevention and preparedness, including the
risk assessment process.

m) The Resources Needed to Maintain the Drinking
Water System and Quality Management System
Water Services currently has one full-time Quality Management Specialist, who is also the
Quality Management System Representative. Everyone at Water Services plays a role in
ensuring the success of the Quality Management System. Beyond the work of all staff, the
Quality Management Specialist has access to a Water Compliance Specialist; five Water
Services Technicians; a Customer Service Clerk; and a seasonal Records Management
Assistant to ensure that reporting and documentation requirements of the QMS are met.
Operational challenges in the drinking water system continue to drive the need for additional
resources, such as:
• A changing staff profile, with experienced staff that have retired or are due to retire in
the next few years;
• Aging city infrastructure requiring increased capital budget considerations;
• Potential source water supply shortfall (e.g. current supplies not meeting future
demand, drought, contamination and demands of future growth) requiring increased
capital project and budget considerations;
• Distribution system issues (e.g. dead ends in the distribution system, frozen city-side
infrastructure, larger infrastructure failures and aging water meter infrastructure,
aging watermains, watermains located on easements); and
• Private property issues (e.g. substandard water services).
n) Results of Infrastructure Review
The identification of water infrastructure requirements are achieved by reviewing the needs
of existing and new infrastructure through the completion of asset management plans both
at Water Services and corporately.
Distribution Infrastructure Needs
Distribution infrastructure needs are outlined in the corporate Asset Management Plan,
which is developed using industry best management practices and completed by the
Corporate Asset Management group in the Engineering and Transportation Service Division
(Engineering Services). This linear plan is reviewed by Water Services who then assists in
developing a priority sequence for project completion.
2019 Annual and Summary Report
Page 76 of 182
During the annual budget preparation process, Engineering and Water Services review
infrastructure conditions, inventory age, CAPS (capital asset prioritisation system), and
system criticality. From this evaluation, Engineering and Water Services finalize the list of
priority projects that also considers the priorities of wastewater and road reconstruction
projects so that these projects can share the costs of excavation and rehabilitation. New
linear infrastructure reviews are primarily driven by Engineering Services.
Annual summaries of road reconstruction, sewer and watermain projects are identified on a
capital project infrastructure map that is released by Engineering and Transportation
Services early spring each year.
Water Supply and Treatment Facilities Infrastructure Needs
On July 28, 2014 Guelph City Council unanimously approved the Water Supply Master Plan
update, defining preferred water supply servicing alternatives in meeting the needs of
existing customers and future community growth.
In concert with the Water Supply Master Plan Update, the City’s Engineering and
Transportation Services Division completed an update to the linear water distribution
network model as part of the 2014 Development Charges Background Study to define water
distribution improvements needed for growth servicing.
As part of the above mentioned studies, a number of system upgrades have been identified
including: additional water supply sources; new pumping stations; storage facilities; and
new water distribution mains. To help integrate these complex works, the City completed
the Pressure Zone 1 and 2 studies in 2015 and 2017, respectively. These studies support
the implementation of capital projects as outlined in the Water and Wastewater Capital
Budget deliberations.
In 2017, Water Services completed the Water Facility and Property Asset Management Plan.
This Plan identifies and prioritizes capital projects and land acquisitions required to maintain
and renew its existing facility assets and associated operations over a 25 year planning
horizon in accordance with asset management industry best management practices as well
as current codes, guidelines and standards. A 10-year capital forecast for Facility and Water
Plant Upgrades was presented to and endorsed by Council as part of the 2020 Capital
Budget deliberations to address a backlog in infrastructure investment required to sustain
operation of the City’s critical water supply facilities and processes.
As a result of the above noted studies, key capital projects have been initiated/completed in
2019. The following provides the project name with a brief description of these key projects.
2019 Annual and Summary Report
Page 77 of 182
F.M. Woods Station Upgrades and Engine House and Pumping Station
Building Retrofit
In 2019, works were initiated on the F.M Woods Station Upgrades to address critical
infrastructure upgrades and retrofit of the Engine House and Pumping Station Building
(Heritage Building) to provide office space for staff, respectively. 2019 works included the
completion of architectural design of new office space for the Heritage Building, tendering
for consultant selection for the F.M. Woods Upgrades and completion of the reservoir
inspections. The Heritage Building is scheduled for completion in Q4 2020, with the F.M.
Woods Upgrades being completed in 2023.
Burke Well Station Upgrades
Originally built in 1975, Burke well is one of the largest individual wells in the City pumping
about six million litres of water and supplies about 13,000 Guelph households with water
each day. This water treatment plant, completed in Q2 2019, is the first of its kind for the
City, and was constructed to remove iron and manganese from groundwater. Removal of
these metals allow our pipes to stay cleaner longer; therefore, prolonging the life of this
important City asset while also reducing the need for flushing programs and conserving
water. For the community, this new treatment plant will improve overall water quality and
service delivery.
The upgrades include construction of a building to house a pressure filtration system. The
upgrades resulted in a reclassification of the Water System by the MECP for both treatment
and distribution on December 20, 2018. The Guelph Drinking Water System is now classified
as a Class 2 Water Treatment System and a Class 4 Water Distribution System.
Clythe Well Treatment Upgrades and Zone 2 Environmental
Assessment
The Environmental Assessment (EA) was completed for the Clythe Well station in 2018. As a
result, the City purchased a parcel of land in their preferred location, which will house the
new Water Treatment Plant. Design of this treatment plant is anticipated to be initiated in
2020 after the completion of the Zone 2 EA. The Zone 2 EA will determine the need for
future water storage requirements on the East Side of the City which may impact the design
criteria for the new Clythe Well station. The Zone 2 EA is anticipated to be completed in
2020.
Paisley Pumping Station Upgrades
2019 Annual and Summary Report
Page 78 of 182
Upgrades to the Paisley Pumping Station were initiated in 2018 and will be completed in
2021 to ensure asset life is maintained. The scope of this project includes assessment of the
reservoirs, re-alignment of the pipes to accommodate a new watermain connection from
Paisley Road, upgrades to ensure electrical efficiencies and upgrades to the SCADA and MCC
(electrical system). Work is also being completed in preparation for the new Paisley Road
Feeder Main Engineering Project, which will promote redundancy in water distribution to the
west side of the City. In 2019, design of the new pumping station was almost completed
with construction starting in 2020.
Middle Reach of the Aqueduct
In 2018, preliminary projects were completed in preparation for the condition assessment
and potential maintenance of the middle reach of the aqueduct. Studies included completion
of an Environmental Impact Study and key contingency planning for unplanned changes in
water quality including operational responses. Meetings were also held with various
stakeholders including the Township of Puslinch, site neighbours, the Health Unit and the
MECP. It is anticipated that inspection will occur in the summer/fall of 2020 to inform future
capital needs for aqueduct maintenance and renewal. A new laneway will be constructed to
provide operational access to the middle reach in early 2020.
Calico Well Upgrades
Calico Well was taken out of service in August 2018 for scheduled contact chamber cleaning
and inspection. During the cleaning process, the well casing that extends through the
contact chamber was found to be damaged due to material corrosion. The site remains non-
operational as consultant reports and recommendations are being reviewed to determine
the best approach to deal with several process and building related issues. As a result of this
supply being off-line, the section of the feedermain between the station and the City’s
distribution system has been isolated and taken out of service.
Membro Well Upgrades
Upgrades to the Membro Well station were initiated in 2019 to bring the new replacement
well online after receiving the final Permit to Take Water from the Ministry of the
Environment, Conservation and Parks in October 2019. Design of the upgraded facility was
initiated in late 2019 with completion in Q1 2020. Upgrades, in addition to the addition of
the new replacement well, may include the realignment of the UV system and energy
upgrades such as VFDs and lighting. The main upgrades will include the building of an
2019 Annual and Summary Report
Page 79 of 182
addition to the existing well house, pumps and piping to connect the new well to the
distribution system and SCADA programming modifications.
In Q1 2020, a pumping test will be completed at the replacement well to confirm pumping
capacity. This is required to inform the upgrades as noted above. During this test, dye
tracer testing from the nearby sewage lift station will also be completed to determine a
potential bacteria source pathway. This testing will occur for the duration of the pumping
test which is anticipated to be completed in Q2 2020. If the dye is detected before Q2 2020,
the pumping test will continue to determine the influence of this increased water taking on
nearby wells.
Guelph South Feasibility Study
In 2019, the City initiated the feasibility study at the Guelph South test well in order to
evaluate the potential availability of new water supply for future use, as per the Water
Supply Master Plan. Further, the City has also partnered with the University of Guelph on
this project to better understand interactions between the shallow groundwater and surface
water in the area. Works include the installation of a new well in the proximity of the test
well, pumping tests and installation of groundwater and surface water monitoring
equipment. The majority of the work will be completed in 2020.
Logan Well Feasibility Study
In 2019 the City initiated the feasibility study at the Logan well in order to evaluate the
potential availability of new water supply for future use, as per the Water Supply Master
Plan. Works included tree clearing and maintenance of the access laneway in 2019.
Preliminary tests of the well were conducted to determine the condition of the well. The full
work plan will be implemented in 2020 which includes rehabilitation of the well and pumping
tests.
Backflow Prevention Program
Preservation of drinking water quality within Guelph’s infrastructure is supported by the City
of Guelph’s Building Services Division through administration of the Guelph Backflow
Prevention Program and By-law (By-law Number 2016 - 20028). As defined under the By-
law, Backflow means the flowing back of or reversal of the normal direction of flow of water.
The By-law requires that no connections are made to the City’s water supply where a
private premise risk may exist without the installation of an approved backflow prevention
2019 Annual and Summary Report

device to isolate premises, sources, and zones to prevent cross-connections in every
building or structure where a City water supply or other potable water supply exists.
Annually, Building Services provides a Backflow Report, included in Table 36 below, that
tracks the number of letters sent out regarding backflow device annual testing and re-
surveying requirements of the By-law. In accordance with the by-law, failure by property
owners to maintain or replace the backflow prevention would result in the shut-off of water
servicing to the premise to protect the integrity of the City’s water supply.

Appendix C: Total Water Pumped and Instantaneous Flows
This section summarizes the amount of water pumped and instantaneous flows in 2019.
Capacity is calculated by comparing the average pumped or flow value against the MDWL
allowable volume or PTTW flow. Capacity is representative of the conditions of pumping for that
year which may be influenced by other testing programs, maintenance or special operational
conditions. Additionally, the actual capacity of the source may not be achievable with current
infrastructure. Optimization efforts are included as a component of the Water Supply Master Plan
with the intent to match the actual capacity of the water source with the appropriate
infrastructure. Section g) Water Supply Capacity describes capacity in further detail.

Table 51: Management Action Items Identified Between Management Review Meetings, 2019
Item
# Status Description
1 CIR #895 Closed: 2019-05-22
Look at the minimum UVT value at Woods – is it really 93.5% or could it be lower? Verify the setpoints for UVT on SCADA.
2 CIR #894
Closed: 2019-07-25
Consider adding more of the “whys” to SOPs to link the relationships for example, the
relationship between UV dosage, UVT, etc.
3 CIR #893
Consider prioritizing SOPs (for example all SOPs for disinfection get more attention). Consider
adding a physical component to the review of Priority SOPs (i.e. go to the stations and see how the work is done).
4 CIR #892
Closed: 2019-11-28
Review with the Management Team the need for an annual SOP review. Could we review priority SOPs every year and go to a less frequent schedule for the other SOPs, WIs, Reference Documents?

Item #
Status Description
6 CIR #890
Consider having more technical training for Operators from internal staff. For example, have the Hydrogeologist give a presentation on Membro and talks with the Ministry, etc. and the importance of the data that is being collected by Operators. Have the Water Compliance
Specialist give training on compliance requirements for primary disinfection. Consider developing an annual training session on primary disinfection and how the Operator’s duties relate to
achieving primary disinfection. Include on-site manual operations in this training.
7 CIR #925
Closed: 2019-03-25 The well level low shutdown interlock for Queensdale is set too low.
8 CIR #942
Closed: 2019-05-22
In order to ensure that records are easily accessible and protected, consider adding the Reference Document: “Supply Maintenance Critical Equipment Inventory” to EDMS.
Consideration could be given to combining the information from the draft “Standardized Equipment List” on what supplier is used to obtain each part listed in the RD. Consider removing
the “available stock” section to a working document for inventory tracking.
9 CIR #941
With the implementation and increased use of WAM in both Maintenance and Distribution,
consideration could be given to looking at increasing staff support to help with the implementation and development of the program for the whole department.
10 CIR #940
Closed: 2019-10-03
Consider reviewing the process for prioritizing SCADA Work Orders to include Operational staff in
determining the priority.
11 CIR #939
Closed: 2019-05-22

Page 130 of 182
Item #
Status Description
12 CIR #938
Closed: 2019-05-22
The training program for new Operators as identified in QMS 10-03 should include training on chemical receiving as it is a high risk activity from both a treatment perspective and a health and safety perspective.
13 CIR #937 Closed: 2019-07-19
In order to ensure that documents are properly stored and easily accessible, consider putting the Source Water Protection Risk Management Plans on EDMS. This will also help with version
control.
14 CIR #936 Conduct an assessment (gap analysis) of the Emergency Plan to ensure that it is up-to-date and
captures all of the potential emergencies that could impact Water Services.
15 CIR #935
In order to ensure that Water Services maintains a state of emergency preparedness at all
times, consideration should be given to conducting an annual review and update (if necessary) of the Emergency Plan. This review schedule should be captured in the QMS 18 document of the Operational Plan. This is a best management practice as recommended by Emergency
Management Ontario.
16 CIR #934 Closed: 2019-12-12
When the External Auditor arrives on site to perform the annual audit, past OFIs are reviewed to
determine if they have been implemented or are on their way to implementation. If they have not, it generally leads to a non-conformance. As identified as an OFI in the 2017 Internal Audit and as an OFI in the 2018 External Audit, Meter Shop SOPs and WIs need to be finalized from
draft form, properly stored in EDMS and reviewed by staff. The development of a formalized SOP for installation of backflow devices used at hydrants was also identified in the 2018 External
Audit. This has yet to be completed.
2019 Annual and Summary Report
Page 131 of 182
Item #
Status Description
17 CIR #933
If there is a deviation to an already approved construction plan, the changes to the plan need to be properly reviewed and approved by Water Services staff to ensure that risks are identified and monitored throughout the construction project. Consider developing a communication plan
with Engineering so that Water Services staff are kept aware of the changes to plans. For example, on Starwood Drive, the location of the dig changed and contractors were digging
dangerously close to a 12” watermain requiring an emergency response from a Distribution Operator.
18 CIR #932 Closed: 2019-11-28
Standardize a commissioning plan for all contractors to use. Detail out the procedure for disinfection and commissioning and what is required by the contractor. Include in this a requirement of tracking and/or measuring wasted water. This will ensure disinfection and
commissioning consistency among contractors and will benefit Water Services staff to confirm that everything has been done properly.
19 CIR #931
Closed: 2019-07-25
A concern was expressed to determine if hydrants should be used to feed temporary watermains in reconstruction projects. If the drain holes in a hydrant aren’t sealed properly, and if there was a low pressure event causing a backflow/back-siphonage, it may be possible that contaminants
(groundwater) could enter the distribution system from the drain holes in the hydrant. It is suggested that a review of using hydrants to supply water to temporary watermains is
conducted to determine the risk to water quality.
20 CIR #930
Consider modifying the warranty checklist for new construction so that it includes locate
verification of tracer wire. Currently a checklist exists for valves, hydrants, etc. The Locate department can perform Continuity Testing and sign off at the same time that Distribution Operators complete the warranty inspections on new infrastructure.

Status Description
21 CIR #929
Closed: 2019-07-25
Consider upgrading the quality of service boxes specified (i.e. stainless steel) for new construction and service line maintenance. They will last longer and reduce maintenance requirements on broken infrastructure.
22 CIR #928
Closed: 2019-12-09
To ensure that customer service training for new administration employees is consistent amongst all employees and covers all pertinent work instructions and procedures, consider
creating an on-the-job training checklist similar to what exists for Operators, Locators and Meter Installers, which is documented in QMS 10 - Competencies.
23 CIR #927 Closed: 2019-09-27
To improve communications between administration staff and other Water Services work areas, the “on-call” phone for each work area (Distribution, Meters and Locates) should assigned during normal business hours to ensure that someone can always be easily reached. This would also
help with the facilitation of work requests, or general inquiries within the department. For example, the “treatment on-call” phone number is answered 24/7, so if someone from Water
Services needs help from a Water Treatment Operator, they will be assured that they will always reach someone when they call that number regardless of who is on vacation, away at training, or out of the office.
24 CIR #1007 Closed: 2019-07-16
From the Emergency Evacuation Debrief: Investigate the possibility of having an emergency beacon somewhere on site.
25 CIR #1006 Closed: 2019-11-22

Appendix I: Water Efficiency Program – 2019 Annual
Progress Report
Background
The City of Guelph is a leader in water conservation and efficiency. As one of Canada’s
largest communities reliant on a finite groundwater supply for our drinking water needs, our
ability to reclaim water and wastewater serving capacity through conservation initiatives
offers numerous benefits to our community and local ecosystem.
Between 2006 and 2014, 9,520 cubic metres per average day of water and wastewater
capacity was reclaimed due to the successful uptake of the City’s 2009 Water Conservation
and Efficiency Strategy. This reclaimed supply allowed the City to delay the need for over
$41 million in additional water and wastewater infrastructure with an investment of
approximately $11.3 million in water conservation programming, during that timeframe.
Further, the reduction in water use across the city has resulted in a cumulative daily
operational savings of over $625,000 per year in electricity and treatment chemical costs,
creating a significant financial benefit to water rate payers, over the same period. As a
result, the City’s water and wastewater rates remain close to the median of Council-
approved Ontario comparator municipalities responsible for the provision of water and
wastewater services.
In July 2014, Guelph City Council endorsed an updated Water Supply Master Plan (WSMP).
Water servicing capacity reclaimed through conservation and efficiency continued to be a
top priority in achieving a sustainable and cost effective community water supply. The
WSMP established a new reduction target of 9,147 cubic metres in average daily production
by 2038 to guide the City’s water efficiency programming.
In support of the new reduction target, staff initiated an update in 2015 to the 2009 Water
Conservation and Efficiency Strategy, which was later approval by Guelph City Council in
2016. The 2016 Water Efficiency Strategy defines the programs, policies and resources that
will help Guelph meet WSMP reduction targets.
The following sections provide an update of the water conservation and efficiency program
activities and successes of the 2016 Water Efficiency Strategy for the period of January 1
to December 31, 2019. For more information on the City’s Water Efficiency Program and
individual program resources please visit guelph.ca/ourstoconserve.
2019 Annual and Summary Report
Page 148 of 182
Water Reduction Target Progress
Building off the data analysis completed for the 2014 Water Supply Master Plan, the 2016
Water Efficiency Strategy (WES) identified a ten-year water savings goal of 6,265 cubic
metres per day between 2017 and 2026. The updated Strategy anticipates a considerable
amount of supply capacity can be reclaimed through water loss management (i.e. Leak
Detection and District Metered Areas) and efficiencies realized within the industrial,
commercial and institutional sector.
Based on community uptake and participation in new and enhanced water efficiency
programs, the total water savings achieved for 2019 was 658.5 cubic metres per day,
surpassing this year’s target set in the WES. Based on reductions in energy needed for
water treatment and distribution, it is anticipated that 47.7 tonnes of greenhouse gas
emissions and over $48,000 in electricity costs will be avoided through this year’s water
savings. Since the implementation of the 2016 WES, the cumulative water savings achieved
to date is 1,105 cubic metres per day.
Figure 6 presents the anticipated volumetric production values as presented in the 2014
Water Supply Master Plan and the 2016 Water Efficiency Strategy. The City continues to
experience a positive differential between projected and actual production values. Actual
average daily production tracks below that expected through the Water Supply Master Plan.
This is due, in part, to the successful implementation of the 2016 WES and 2009 Water
Conservation and Efficiency Strategy Update.

Figure 7 presents the City of Guelph's residential water use between 2014 and 2018,
calculated using the volumetric consumption of water of all residential properties – low,
medium and high density. During this period the City of Guelph’s residential water use has
been on a downwards trend, at an approximate rate of 3.25 litres per person per day
annually. That is enough water to fill 66 Olympic swimming pools each year.
Average daily residential water use in Guelph continues to remain below the provincial and
national averages. In 2018, the average water use was 156 litres per person per day,
whereas the most recently published average for Ontario is 184 and Canada is 220 litres per
person per day.
2019 Annual and Summary Report
Page 151 of 182
The following sections outline the individual program successes for 2019, as identified in the
2016 WES.
Water Efficiency Incentive and Rebate Programs
During 2019, 984 rebate applications and audits were completed through the City’s
residential rebate programs. An additional 38 incentives for municipal and business
upgrades were processed. For more information on the individual water efficiency programs
available, visit guelph.ca/rebates.
Royal Flush Toilet Rebate Program
The Royal Flush Toilet Rebate Program offers households a $50 rebate per toilet (up to two
toilets) when 6 litre per flush or higher flush volume toilets are replaced with a model using
only 4.8 litres per flush or less. This program encourages residents to upgrade older homes
to meet current building code standards and reduce their actual water use permanently
through fixture exchanges. A total 668 toilet rebates were claimed in 2019, achieving an in-
year water savings of 26 cubic metres per day. This meets the Strategy’s 2019 goal for the
program savings.
Residential Sub-Water Meter Rebate Program
Sub-water meters identify water leaks and high water-using behaviours, creating awareness
of water use and potential cost savings for property owners (i.e. homeowners, landlords,
property managers). Sub-water meters provide specific information on water use at
properties and help in creating measurable conservation challenges and goals for property
owners and tenants. This offers significant opportunities for motivating behaviour change
since a knowledge gap often exists in regards to how much water residents actually use.
The Residential Sub-Water Meter Rebate program offers up to half the cost of a qualified
meter to a maximum of $100 per sub-meter installed. In 2019 the program participation
rates were low, seeing only four eligible applications. Of the participants, three were for
multi-residential buildings and one for single family detached home.
Since January 2018, associated water savings for program participants is on average a 12
per cent reduction in total water use. These measured savings are in range with industry
expectations (ten per cent) and significantly above the three per cent average savings
witnessed in the program pilot. While program participation was down in through 2019, the
2019 Annual and Summary Report
Page 152 of 182
program has saved approximately 7.8 cubic metres per day. This is ahead of the five-year
target of five cubic metres per day.
A robust and innovative approach to program promotion is scheduled for Spring 2020 to
increase enrollment and meet program water-saving goals.
Water Use Home Visit and Audit Program
The home audit program provides a unique opportunity to engage Guelph residents one-on-
one to understand water using behaviours and habits. These visits assist homeowners in
verifying water use of fixtures and appliances and provide individualized feedback on tools,
techniques and behaviour changes to become more water efficient in their home.
Since November 2013, eMERGE has made the Home Tune-up program available to Guelph
residents. The Home Tune-up program is an innovative collaboration between eMERGE
Guelph Sustainability, the City of Guelph and other local partners. This service offers a free
one-hour home audit by trained advisors, a complimentary retrofit of common home water
use fixtures (such as water efficient showerheads and faucet aerators), and toilet leak
detection. Each participating household receives an Action Plan; a personalized electronic
report that provides information and suggestions to help reduce home resource use. The
action plan directs Home Tune-up participants to further resources and tools, including City
programs, to assist with the implementation of recommended improvements.
In verifying the household water consumption data, homeowners who receive the visit have
reduced their average water consumption by up to 10 per cent depending on the retrofit
measures taken. To date, eMERGE home visits have engaged 1,659 households with a home
audit since 2013.
The eMERGE Home Visit service engaged 109 single-family households and eight multi-
residential buildings, comprised of a total 185 units in 2019, for a total 292 Home Tune-ups.
The single-family homes achieved an average in-year household water savings of 4.73 cubic
metres per day. This value is down from the 13 cubic metre per day goal outlined in the
Strategy. However, this does not account for savings from multi-residential properties. As
Home Tune-up’s for multi-residential properties occurred later in the year, work is ongoing
to determine water savings from these property types.
In 2020, staff will continue to promote the Home Tune-up program alongside Blue Built
Home to boost both programs by feeding off each other’s success.

Blue Built Home Water Efficiency Standards and Rebate Program
The Blue Built Home (BBH) Water Efficiency Standards and Rebate Program is a voluntary
construction and retrofit standard designed to outperform the plumbing and water–using
fixture requirements of the Ontario Building Code. The installation of water efficient
technologies contributes to reduced water use in single-family detached homes and multi-
residential properties. Residents with certified Blue Built Homes will save water and reduce
utility bills by 15 to 62 per cent. From launch in 2010 until year-end 2017, 50 new homes
were Blue Built Home certified in one of three tiers: 44 Bronze, 4 Silver and 2 Gold.
In 2018, Blue Built Home was updated and relaunched. Program changes included a
transition to a single-tier program and certification and associated rebates were made
available to existing, new homes and the multi-residential community. With these program
modifications, eleven single-family homes (ten retrofit and one new build) were Blue Built
Home certified within the year.
In 2019, six single-family homes (two new build and four retrofits) were Blue Built Home
certified. Together these homes are saving 0.27 cubic metres per day or 97.8 cubic metres
each year. However, significant water savings are achieved by an additional four new multi-
residential buildings that were Blue Built Home certified as a pilot, which together save a
total of 6.9 cubic metres per day. This makes the total water savings for Blue Built Home in
2019 7.17 cubic metres per day, more than triple our water savings goal for 2019.
In Q1 2020, it is planned that staff will officially launch the Blue Built Home program for
new-build multi-residential properties and continue to pursue the significant savings
associated with sustainable growth.
Multi-Residential Water Audit Program
The Multi-Residential Water Audit program offers a no-cost water audit of Guelph’s multi-
residential apartment and condominium buildings completed by a third party consultant. The
audit includes an assessment of the whole building’s water use and verification of specific
water using processes, such and pools, central cooling and irrigation systems. A
proportionate number of units of each building are audited to identify water saving
opportunities across the remainder of the suites.
Building owners or property managers are provided a final report cataloguing all water using
fixtures, appliances and processes with tailored recommendations to help reduce their water
bill. Staff meet with property owners and/or condominium boards to review available
rebates to achieve the noted savings. In 2019, eligibility for the Multi-Residential Water
2019 Annual and Summary Report
Page 154 of 182
Audit Program was updated to expand eligibility to properties using an average of 130 cubic
metres or more per unit, per year.
This year, the Multi-Residential Water Audit Program had ten participants, an increase from
three the previous year. The main findings from all audits performed in 2019 were as
follows:
Leaks
• Detected in 90 per cent of buildings audited
• Accounted for 2.5 to 16.3 per cent of buildings’ total water use
• 9,130 cubic metres of leaks detected collectively in 2019
• Estimate 25.0 cubic metres per day in water savings would result from
implementation of audit recommendations
Water Savings Opportunities (including leaks)
• Account for 13.9 to 31.8 per cent of total building water use
• 22,258 cubic metres of water savings potential was identified across ten participating
properties in 2019
• Estimate 61.0 cubic metres per day in water savings would result from
implementation of audit recommendations
In order to calculate savings associated with the program, an annual assessment of
consumption is completed, which requires data from the following year. With this in mind,
the three program participants of 2018 achieved a verified water savings of 24.3 per cent,
or 15.84 cubic metres per day. This significant savings may be attributable to “early
adopters” and may not reflect the true average of all possible multi-residential building
potential.
Staff have taken a conservative approach to estimating savings associated with 2019
program participants. Assuming a ten per cent decrease in water use (as per the WES),
29.4 cubic metres of water per day have been reclaimed through 2019 participation. This
provides a combined water savings of 45.24 cubic metres per day since launch of the
program in 2018, eight cubic metres more than the anticipate program goal to-date. The
estimated savings will be confirmed and reflected in subsequent annual reports.
Water Smart Business Program
The Water Smart Business program offers support to local businesses toward completion of
a detailed water efficiency review, and offers incentives for the completion of third-party
water audits and funding for capital retrofits that permanently reduce water demand. The
2019 Annual and Summary Report
Page 155 of 182
audit benchmarks the water consumption of the businesses and provides a report with
recommendations that include estimated payback on investment in upgrades. Once the
business undertakes a recommendation that achieves water savings, the savings are then
verified and an incentive is issued (where qualifications met).
In 2019, Water Smart Business program actively engaged seven program participants
through either a water review, audit and/or capital project incentive. The following are the
summarized results:
Leaks
• Detected in 29 per cent of businesses visited
• Accounted for 17.5 to 53.5 per cent of business’ total water use
• 3,910 cubic metres of leaks detected collectively in 2019
• Estimate 10.2 cubic metres per day in water savings
Water Savings Opportunities (including leaks)
• Account for 6.9 to 25.3 per cent of total facility’s water use
• 10,442 cubic metres of water savings potential was identified across seven
participating businesses in 2019
• Estimate 28.6 cubic metres per day in water savings would result
One program participant in 2019 was incentivized through the Water Smart Business
program for an ice-machine upgrade, which has resulted in 3.5 cubic metres per day of
verified water savings through process upgrades.
Outside the formal scope of the Water Smart Business program, two additional program
touch-points realized significant water savings associated with leaks for two industrial
facilities in Guelph. These included:
• Sourcing a ten-year private side leak resulted in a 47.1 cubic metres per day in
consumptive savings; and
• Cooling tower leak that, had it gone unresolved, would have resulted 4.98 cubic
metres of water per day.
Further to that, staff hosted an event for local businesses in December to learn more about
the Water Smart Business program. Water Smart for Guelph Restaurants and Hospitality
Sector lunch-and-learn was hosted at a local restaurant. Twenty-one representatives
spanning various hospitality businesses confirmed their attendance despite this busy time of
year for the sector. Meetings with those who expressed interest but could not attend will be
held in Q1 2020 and indicate a high probability of sector interest in program participation
through 2020.
2019 Annual and Summary Report
Page 156 of 182
Staff continue to consider enhancements to the program to entice businesses, including
commercial plaza water users – a sector typically bulk-metered where by individual
businesses within are not accountable for their water use directly. Since the launch of the
Residential Sub-Water Meter Rebate program staff have received inquiries and requests
related to sub-water metering primarily from the commercial sector. In 2019, staff
commenced preliminary research to evaluate the water saving potential (if any) of this
technology within this sector. Evaluation includes assessing municipal examples of similar
programs, determining value for parties involved, participation and program costs to
establish a business case for Guelph to pursue. This research will be completed by Q2 2020.
Overall, Water Smart Business program water savings since the 2016 Water Efficiency
Strategy have resulted in 65.87 cubic metres per day; 15 per cent of the cumulative five-
year program goal. Staff are committed to finding new and unique ways to see water saving
projects come to fruition. In 2020, staff will be focusing efforts on key business and industry
types in the community (i.e. food, beverage, hospitality and commercial plazas) where
messaging can be tailored to increase program participation.
Cooling Tower Research
The 2016 Water Efficiency Strategy recommended City staff assess participation, cost and
water savings associated with a cooling tower audit, conductivity censor and meter rebate
pilot. A sample size of at least five buildings were recommended to be studied in order to
verify savings and costs effectiveness of the program. The following sections describe
research conducted in 2019 in support of program development:
The Water Efficiency Strategy includes a proposed multi-year budget of $120,000 CAD
(2021 to 2026) to establish the parameters of a program as well as fund the completion of
cooling tower audits and offer an incentive for upgrading.
Alliance for Water Efficiency Cooling Tower Research Project
In 2017, the Alliance for Water Efficiency (AWE) commenced a Cooling Tower Research
project. The overall purpose of this study is to gain foundational knowledge needed to
create an effective, targeted, and appealing incentive and outreach program to achieve
greater efficiency in industrial cooling systems. As part of AWE’s broader effort to explore
the potential for water conservation in urban areas, the research effort is intended to have
multiple phases.
Phase I has five broad goals:
2019 Annual and Summary Report
Page 157 of 182
• Develop best practices for identifying water-cooled facilities in urban areas.
• Develop best practices for estimating consumptive and non-consumptive water
demands for cooling.
• Determine the conservation potential for improvements to traditional cooling
technologies, such as cooling towers.
• Determine the conservation potential of alternative cooling technologies.
• Develop practical guides to increase understanding of cooling technologies.
Thirteen municipalities and utilities from across North America have signed on including
Denver Water, Southern Nevada Water Authority and San Antonio Water System in this
multi-tasked project.
In 2019, initial data collection was completed and modelling commenced to develop best
practices for identifying water cooled facilities in urban centres. This research component is
intended to be available for the municipal and utility project team to test in early 2020.
The results of this research will provide the framework for the proposed cooling tower audit
and rebate program. While the timeline has been accelerated from that outlined in the WES,
the City’s total investment of $28,000 in this leading North American research project will
provide a well-researched, value-for-dollar scope for local programming (a total project
budget of $530,000CAD; $400,000USD). Due to issues in sourcing a research facility to
complete the work, this project is now scheduled for completion in early 2021 in line with
the WES update and timing for recommended program roll-out.
Legionella
Further to the research being completed through the Alliance for Water Efficiency, industry-
leading technical associations and working groups are beginning to explore the implications
of properly managed cooling towers, reuse and concerns around public health related to
stagnant heated water. As such, staff commenced preliminary research related to the
effects of cooling tower water efficiency, specifically water age and quality, in industrial,
commercial and institutional buildings. These two things can be contributing factors that
lead to micro bacterial growth with one of those being Legionella.
Staff attended the National Legionella Conference (United States of America) to provide a
clearer definition of the municipal role in managing for Legionella bacteria, the relationship
between water efficiency and legionella, and any potential nexuses that exists. Through the
update to the Water Efficiency Strategy commencing in 2021, a larger evaluation will need
to be considered related to water reuse in cooling towers to ensure program
recommendations appropriately evaluate risk and protect public health.
2019 Annual and Summary Report
Page 158 of 182
Municipal Facility Water Efficiency
In support of the Water Efficiency Strategy, the City continues to lead by example with
water efficiency within its own facilities. Recreation centre and facility managers and
maintainers participated with staff in seven water use reviews, audits and capital
infrastructure upgrades to improve the efficiency of their buildings.
In 2019, the River Run Centre, Guelph Farmer’s Market, John McCrae House and the Civic
Museum each completed a water review with program staff. In support of facility upgrades
completed by Parks and Recreation and Corporate Energy program staff completed two
additional water-using process reviews: Norm Jary Splash Pad and West End Recreation
Centre. Lastly, a third-party engineering consulting firm was hired to complete a water audit
of the Sleeman Centre. The following are the cumulative results:
Leaks
• Detected in 50 per cent of municipal facilities visited
• Accounted for 7.1 to 11.1 per cent of buildings’ total water use
• 1,167 cubic metres of leaks detected collectively in 2019
• Estimate 3.1 cubic metres per day in water savings
Water Savings Opportunities (including leaks):
• Account for 6.1 to 60.1 of total facilities water use
• 7,553.7 cubic metres of water savings potential per year was identified across seven
municipal locations
• Estimate 65.69 cubic metres per day in water savings would result if audit
recommendations were implemented.
In 2019, 46.22 cubic metres per day of verified water savings through process upgrades
were achieved across four of the municipal facilities and locations. 2019’s municipal water
efficiency upgrades were:
• Norm Jary Splash Pad recirculation system
• West End Recreation Centre pool heat recovery system
• River Run Centre toilet and faucet aerator upgrades
• Guelph Farmer’s Market faucet aerator installation.
These upgrades have exceeded the annual program savings goal for 2019, and the program
is on track to exceed the five-year goal.
Leak Detection Program
2019 Annual and Summary Report
Page 159 of 182
The City’s leak detection program started in the spring of 2011 and aims to reduce the
amount of water lost between the point of treatment and delivery to customers. The 2019
Leak Detection Program included sounding and correlation of all 342 kilometers of metallic
watermains within the City’s distribution system. In total, 33 possible leaks were identified
through this survey, including 14 main breaks and the rest consisting of hydrant, service, or
valve repair/replacements, or no leaks were found. The average daily volume of servicing
capacity reclaimed through the location and remediation of these leaks equate to
approximately 534 cubic metres per day, enough to fill almost 78 Olympic swimming pools
in 2019. The water loss management program savings goal for the year was exceeded.
It is anticipated that further recoveries in reclaimed treated water lost to the distribution
system will be achieved with the continued optimization of the City’s district metered areas
(DMAs). The objective of the DMA program is enhance operational understanding of water
demand patterns and to recognize water demand changes early to address non-revenue
water loss in the water distribution system. In recognition of benefits offered through
continuous water demand monitoring as proactive water loss management, staff will be
continuing to refine the DMAs and develop associated trend analysis tools through 2020.
Peak Season Water Demand Management
Reduction of peak season (summer) water demand continues to be a primary objective of
the City’s water efficiency programming. The ability to reduce or minimize variations in
seasonal water use limits the impact on our finite groundwater supply during times of
environmental stress and creates operational efficiencies by reducing capital and operational
investment to service our community for only a few days a year.
Outside Water Use Program
Since 2002, the City’s Outside Water Use Program (OWUP) has helped to manage peak
season (summer) water use through regulatory controls with complementary programs,
such as Healthy Landscapes, working to proactively manage potential peak demands by
assisting residents and local businesses in establishing low outdoor water use environments.
The following activities were completed as part of this program in 2019.
There was limited precipitation in June and July of 2019. Even with the large rain event on
July 17, precipitation was 60 per cent of 30 year precipitation average for the month.
Because of this sustained dry spell, the Outside Water Use Program moved to Level 1
(Yellow) on July 29. The remainder of the summer was dry, however conditions improved
into the fall season, which finished the season in Level 0 (Blue) on October 2.

Rain barrels offer homeowners the benefit of capturing free volumes of water for outside use
but also assist in managing stormwater impacts on private property. This year’s annual rain
barrel truckload sale was held at Water Services’ open house in May and yielded the sale of
950 rain barrels – the largest number of rain barrels sold during any of the previous years.
This year’s sale was in partnership with Stormwater Engineering. The Engineering
department through the Stormwater utility subsidized the cost of the barrels and the first
850 barrels were sold to residents for $10.
Please visit the City of Guelph Webpage for more information on the Outside Water Use
Program.
Healthy Landscapes
The Healthy Landscapes Program continues to offer various public resources to proactively
manage peak season demand.
The annual Healthy Landscapes Workshops and Seminar Series featured numerous free
talks on time–of–year appropriate outdoor water conservation topics including water
efficient landscape design, plant selection, and proactive maintenance best practices to
manage the impact of drought and common turf pests. It is estimated over 500 Guelph
residents took part in this Workshop and Seminar series. Further, 100 individuals
participated in the annual four-part Landscape Design Course.
Healthy Landscapes visits continue to be a popular resource, with 300 complimentary
one hour visits completed by trained staff this year. This service offers a complementary
site-based consultation aiming to educate residents on garden design and maintenance
practices to significantly curb outdoor water demand at their home.
Healthy Landscapes visits continued to add the Blue Built Home Landscape Visit to the
programming. Homeowners sign up for this specialized visit to complete one of three
qualifying water saving options to become Blue Built Home certified. Twenty Healthy
Landscape visits of this type were completed in 2019.
In 2019, Healthy Landscapes also collaborated with the Stormwater Engineering to pilot a
Residential Rain Garden Rebate program. Two workshops were organized that required
participants to attend to be a part of the program. A total of 50 participants attended the
workshops. Through the workshop, 30 residents were prequalified for the pilot program and
given a rain garden visit with a professional landscape consultant. With this site visit, a
resident could determine how best to install his or her own rain garden. Once the rain
garden was completed and a final verification visit was given, a one-time rebate from the
2019 Annual and Summary Report
Page 161 of 182
City was awarded. Out of these 30 residents, 16 completed the installation of a rain garden
and received their rebates. This resulted in:
• a combined capacity of over 39,800L of stormwater captured with an average rain
gardens capacity of approximately 2,490L;
• the potential garden and lawn watering offset typically relied on for municipal supply;
• over $13,800 in rebates provided with an average rebate of $867.
In anticipation for the program to be offered again in 2020, there are 71 residents on a
contact list. It is anticipated for the program to be offered again in 2020.
Visit the City of Guelph webpage for more information on the Healthy Landscapes Program.
Peak Season Water Demand Research
Staff continue to pursue collaborative research opportunities where resources can be
leveraged to garner greater products. This year, staff collaborated in a project with the
University of Guelph to find alternative plants to use as groundcover to traditional grass
seed and sod. This three-year research project will evaluate alternative groundcovers and
varieties of turf grass to determine their water use requirements and suitability for use in
local urban residential lawn areas. The first season (2019) of research results were
inconclusive due to weed encroachment, low germination rate of some species, and a rain-
out shelter was not constructed in time for the growing season. These issues will be
addressed moving forward, data collected and reported to inform future peak season
demand programming for Guelph. This research project will be ongoing until 2022.
Youth and Public Outreach and Education Programming
Education is a fundamentally important tool to engage and motivate action. The
commitment to increasing local water literacy is a complimentary piece to changing toilets,
or completing water audits, or installing water meters, to ensure the wise use of the
resource. Staff continue to offer a variety of very successful programs to increase
awareness, influence people’s attitudes and habits regarding water use, and inform public
on how the City invests their rate dollars. Investment in Guelph’s water future includes
education and outreach programming.
Curriculum-Linked Education Programming
The City’s curriculum-based Grade 2 and Grade 8 in-class, water conservation programming
continues to be a popular resource for local educators in both the Upper Grand District
2019 Annual and Summary Report
Page 162 of 182
School Board and the Wellington Catholic District School Board. In 2019, staff provided 70
interactive school presentations to 1,459 students. Since the inception of this in-class,
curriculum-linked program eight years ago, the City has provided a total of 411 school
presentations to over 14,620 students.
In addition to in-class presentations, Water Services hosted 32 classes and over 690
students and teachers to tour the F.M. Woods Water Treatment Plant in 2019.
H2Awesome
After a one-year break, this award-winning water event for Guelph’s Grade 8 students
reconvened in 2019. This curriculum-based learning event hosted in partnership with the
local school boards is an opportunity to celebrate water, encourage conservation of the
resource, and provide focus to the importance of water in our daily lives.
The 2019 event saw H2Awesome take place in 2 phases. Phase 1 took place on April 30,
gathering approximately 570 students and teachers to War Memorial Hall on the University
of Guelph campus. The event was co-hosted by two students representing both the Catholic
and Public School Boards. Local Anishinaabe Metis, Jan Sherman, opened and closed the
event with a traditional aboriginal acknowledgement, followed by keynote speakers Emily De
Sousa, marine conservation educator, and The Water Brothers, Tyler and Alex Mifflin.
Phase 2 of H2Awesome included a half-day workshop hosted in their schools from May 1
through May 15, for each of the 222 classes registered for the event. Workshops were
designed for grade 8 students and were participatory activities linked to water through art,
science and technology.
Splitting this event into separate phases was a departure from past H2Awesome events
typically held over the course of a single school day at one venue. The planning committee
felt that the logistics and delivery of the water conservation and protection message was
well suited to this approach. The event received positive feedback from participating
teachers.
Planning has begun for H2Awesome in 2020, and will look to use the same format.
Planet Protectors
Since 2016, Water Services has partnered with Engineering and Transportation Services and
the Office of Climate Change to offer a curriculum-focused, interactive and activity-based
online program called Planet Protectors. This program helps students understand the basics
of climate change, the impact of our actions, as well as the importance of energy and water
2019 Annual and Summary Report
Page 163 of 182
conservation, and transportation choices. Through ‘missions’, Planet Protectors solicits
personal commitments from students and encourages sharing them with their family
members - commitments such as shortening shower time.
The 2018/19 school-year witnessed a reduction in participation, however still saw the
program utilized in 26 classrooms, reaching 566 students in both the Upper Grand District
School Board and the Wellington Catholic District School Board.
As program use stagnates it will be prudent to determine whether the program offers the
best value per dollar spent. At this time other educational program offerings have not
demonstrated additional value or capacity above and beyond what Planet Protectors
Academy offers. Staff continue to evaluate value for dollar.
In 2019 Planet Protectors created H2Whoa, a four part program focusing solely on water –
decoupling water content from the broader program offering. Water Services will continue
their relationship with the Planet Protectors through the H2Whoa program in 2019/2020
school year, with the intent of monitoring appetite and delivery of the new, water focused
material.
Other Outreach and Engagement Programming
H2O Go Festival
2019 H2O Go Festival (hosted by the City) celebrated its seventh year of programming. This
Festival is a community celebration of water, hosting a variety of educational and interactive
displays aimed at connecting audiences of all ages with water. The Festival runs in tandem
with the eMERGE Guelph EcoMarket – a sustainability expo.
This year’s H2O Go hosted nine organizations, collaborating with local not-for-profits,
businesses and institutions. Hosted at the Old Quebec Street Shoppes, attendance has
continued to grow each year. This year’s event attracted over 3,000 participants of all ages
(800 more than the year prior).
Coordinated planning for the 2020 event has begun with the event to take place at the Old
Quebec Street Shoppes in downtown Guelph on Saturday, March 21, 2020.
Waterloo Wellington Children’s Groundwater Festival
Celebrating its 24th year, the long-standing Waterloo Wellington Children’s Groundwater
Festival was held from May 24 to May 30 in 2019. Water Services is proud to be an ongoing
2019 Annual and Summary Report
Page 164 of 182
partner, sponsor, contributor and organizer of the Festival. In 2019, the Festival engaged
4,898 students Grades 2 through 5 from the City of Guelph, Wellington County, and the
Region of Waterloo. Upwards of 900 students participate from Guelph on an annual basis.
Since 1996, over 95,000 students have participated in the Festival, which features fun and
interactive activities designed to inform students of the importance of water protection and
conservation in their daily lives. In partnership with Guelph’s school boards, staff have
worked to increase local awareness and participation in this Festival annually.
Outreach to New Canadians in Guelph
To build trust in governments’ management of drinking water amongst new Canadians and
introduce new Guelph residents to the City’s unique water supply and constraints, continued
public education programming is encouraged within the community.
Two Linamar facilities implemented an initiative to reduce the amount of disposable plastic
water bottles purchased and used by their staff in 2019. Reducing plastic water bottle use
minimizes Linamar’s environmental impact and promotes a safe and clean working
environment by eliminating workstation clutter within the plants due to empty, or partially
empty, plastic bottle accumulation. Linamar approached Water Services about providing an
educational presentation about Guelph’s water to support this project. Linamar staff
demographics are highly multicultural and are largely comprised of new community
members to Canada and Guelph. Linamar believed this educational component would be a
key to the success of their project.
The two locations installed additional water fountains to improve accessibility to tap water
and provided each staff member with their own reusable, stainless-steel water bottle. To
enhance the initiative’s success, Water Services gave a 15-minute presentation to all staff
members at participating facilities on Guelph’s water supply during their monthly staff
meetings. Presentation content included the role of Water Services in the community and
our drinking water’s source, treatment, safety, and quality. In total, 840 staff members
received the presentation.
Our tap water presentation built confidence in our tap water’s safety and quality and was an
important component in the success of Linamar’s initiative. There is significant potential for
this initiative to have spillover effects into the personal lives of Linamar’s staff. Ideally,
Linamar staff will confidently choose to drink tap over bottled water at home as well as at
work, and encourage family members and friends to do so.
Water-Energy Nexus Research
2019 Annual and Summary Report
Page 165 of 182
Collectively, Water and Wastewater utilities (i.e. treatment and conveyance) are among the
largest energy consumers by sector in Ontario. Water requires energy intensive treatment
and pumping to maintain a reliable water supply while protecting public health and the
environment. Consequently, water conservation and efficiency presents significant energy
saving opportunities. Furthermore, the cost to expand water and energy infrastructure
emphasizes that conservation and efficiency are among the most cost effective sources of
water and energy. As electricity costs continue to rise and population growth increases
water resource demands, conservation is important for Ontario municipalities to limit the
increasing cost to produce safe clean drinking water and meet energy needs in a time when
climate resilience is required. The water-energy nexus offers new opportunities to save
water, energy and money through reduced infrastructure costs, greenhouse gas emissions,
and operational and maintenance costs.
In 2019, Water Services began to apply the water-energy nexus concept to communicate
associated water, energy and cost savings as identified in the Water Efficiency Strategy. The
intent in doing so could lead to further decreases in water use.
Further to this, staff commenced the practical assessment of renewable energy applications
to the infrastructure related to pumping, treating and distributing water, in alignment with
the City’s Community Energy Initiative. Renewable energy applications for water
infrastructure are rapidly evolving and have the potential to reduce the water sector’s
dependency on fossil fuel–based electricity use.
As a continuation from the 2018 work, Water Services continued to assess energy
optimization opportunities within the drinking water system. In doing so, this information
informs budget forecasting, proposed water rate changes, and to assess the efficacy of
water conservation and efficiency programs. The Water Efficiency Strategy challenges staff
to evaluate opportunities to strategically implement technologies to maximize the use of
available water supply. Staff currently utilize a suite of tools such as water audits, acoustic
leak detection and district metered areas to recover water losses. Water loss management is
known to be a highly cost effective water conservation and efficiency measure for
municipalities as they defer the associated costs of water infrastructure expansion. This
evaluation is anticipated to continue through the 2020 Water Supply Mater Plan update
process.
Guelph Water Wagon
In support of the City’s 2009 Public Promotion Action Plan for City Drinking Water
Consumption, the Guelph Water Wagon has been providing tap water to attendees of large,
2019 Annual and Summary Report
Page 166 of 182
outdoor community events during the summer months for seven years. The Water Wagon
provides access to tap water where water fountains or taps are not readily available.
Continually growing in demand year-after-year, the Water Wagon attended 33 events in
2019 and provided 22,332 litres of water to event attendees. The Water Wagon continues to
provide staff an excellent opportunity to engage with the public. Staff engage with Guelph
residents about:
• the value of Guelph’s water;
• the need for water conservation and source protection;
• questions and concerns regarding municipal tap water;
• Water Services-based public processes, programs and studies; and
• promote tap water consumption over other beverages.
In 2019, staff developed a Water Wagon Communication Plan that will undergo
implementation in 2020. The Communication Plan was developed using insights from the
2018 Water Efficiency Public Education and Communication Strategy and associated market
research, as well as Community Based Social Marketing principles. The Communication Plan:
• identifies specific goals and objectives for public engagement at the Water Wagon,
• clarifies key messages and target audiences,
• details how the Water Wagon Program Coordinator interacts with the public and set-
up their display,
• outlines communication material development, and
• provides direction for monitoring public engagement.
This formal, strategically developed communication plan will be an important guide moving
forward to ensure public engagement efforts via the Water Wagon program remain
consistent, on-point, and contribute to our overarching goals. This resource will be
especially advantageous for assisting the Water Wagon Program Assistant, who is a new
staff member each summer, quickly and successfully navigate their role.
Water Softener Alternatives Testing and Market Research
With high levels of naturally occurring hardness in the City’s groundwater source, the use of
residential ion-exchange (salt-based) water softener technologies is quite common amongst
Guelph households. It is estimated that approximately 77 per cent of local households, as
part of a 2009 residential call survey, use a water softener.
The Region of Waterloo and the City of Guelph financed ground-breaking research in 2015
to assess the performance of an alternative to ion-exchange softening technology that
treats hard water without the need for salt and recharge water. This technology referred to
2019 Annual and Summary Report
Page 167 of 182
as salt and water free technology through the use of: media induced crystallization
(nucleation assisted crystallization (NAC) and template assisted crystallization (TAC));
electromagnetic water treatment (MWT); chemical conditioning with complexing; or
chelating agents. Salt and water free technology employs a combination of processes to
prevent scale buildup in household water heaters and appliances. However, these
technologies do not allow for the same lathering effect as salt-based water softeners
provide.
In June 2017, the City of Guelph again collaborated with the Region of Waterloo to continue
the research, trialling the NAC/TAC technology in real life scenarios. The aim of this study
was to assess the field performance and user benefits associated with salt and water free
residential water softener treatment technology.
Through this study, social research in both communities were completed (phone surveys,
focus groups) to generate a technology test group of 18 homes, to install a single
technology in their home for testing of user experience.
The technology was installed in participating homes by December 2017. Use of the systems
continued throughout 2018. Participants were engaged to provide feedback through
subsequent focus groups and an online discussion board. The final focus group concluded in
January 2019.
The final report was completed in September. The results of the Water Conditioner Study
were posted to the joint website, watersoftenerfacts.ca in November. The results of the
study will be used to inform the update to the Water Efficiency Strategy moving forward.

Appendix J: Water Services Committees
Water Conservation and Efficiency Public Advisory Committee –
Annual Report
The Water Conservation and Efficiency Public Advisory Committee (WCEPAC) – a Guelph
Committee of Council – was formed in 2009 through Council approval. Council recommitted
to this Committee in 2016 with the approval of the Water Efficiency Strategy update. This
committee provides a forum for community input and guidance throughout the City’s
implementation of the Water Efficiency Strategy.
The WCEPAC met four times in 2019. The WCEPAC continues to provide valued insights on
opportunities for continued enhancement of current and developing water conservation
programming, policy and education, engagement and outreach resources. In alignment with
Council reporting requirements outlined in the committee’s Terms of Reference, this Annual
Report details activities of the WCEPAC within 2019.
Water Conservation and Efficiency Public Advisory Committee continued to provide
invaluable citizen feedback and recommendations to enhance the City of Guelph’s successful
water efficiency program, including:
• Feedback on the following water efficiency programs that were updated or developed
as directed through the 2016 Water Efficiency Strategy:
▪ Blue Built Home Water Efficiency Standard and Rebate Program,
▪ Residential Sub-meter Rebate Program,
▪ Integrated Water Mapping Project, including key performance indicators, and
▪ Residential Rain Garden Pilot Project
• Comment on various innovative research, study and pilots including the residential
water conditioner study (related to residential water softener impacts) and the
Assimilative Capacity and Reclaimed Water Feasibility Studies which were conducted
in partnership with Wastewater and Source Water Protection.
• Participation in discussions on how best to utilize and enhance the committee’s
capacity to provide advantageous and quality input.
• Learning opportunities to support member’s role on the committee. This was
especially important in 2019 with four new members joining the committee, and a
new member and City Staff who had joined the committee in 2018. Members received
presentations on WCEPAC roles, responsibilities, policies and procedures; 2016 Water
Efficiency Strategy; Water Supply Master Plan update; Stormwater Management
2019 Annual and Summary Report
Page 169 of 182
Master Plan update; Water and Wastewater Servicing Master Plan update; Guelph’s
Wastewater Treatment operations; and Water Services’ operations.
In 2020, the WCEPAC will continue to be engaged to solicit input throughout continued
implementation of the 2016 Water Efficiency Strategy recommendations including, but not
limited to the following:
• Present an updated Terms of Reference for the Committee, in line with Clerk’s policies
and procedures for Committees of Council (last update in 2009);
• Commencing an update to the Water Efficiency Strategy, contingent upon completing
the Water Supply Master Plan in 2020;
• Outreach and engagement strategies for City of Guelph’s conservation programming
and tap water promotion;
• Development, update, or enhancement to Water Efficiency programs;
• Feedback on the pursuit and application of study results in regards to water reuse,
water energy nexus, and alternative water softening technology; and
• Water Supply Master Plan update.
Visit the Water Conservation and Efficiency Public Advisory Committee webpage for a full list
of the WCEPAC members, meeting minutes and agendas.
The WCEPAC possesses no annual budget. Funding for the City’s Water Efficiency Program is
provided within the Council-approved Non-Tax Supported Water and Wastewater Services
Capital and Operating Budgets as well as through Development Charges.
Well Interference Committee
The Well Interference Committee is a specially arranged—or ad hoc—committee that is
brought together to address well interference complaints resulting from the City’s water
takings.
The committee was established in 2004 to address concerns voiced during the City’s Class
Environmental Assessment for the Arkell Springs Ground Water Supply Strategy. During the
Environmental Assessment, private well owners expressed concern that City water taking
may interfere with or reduce the amount of water available for their wells.
No complaints have gone to the Well Interference Committee since it was established. It is
worth nothing that the Committee convened on May 29, 2019 in order to facilitate an
overview of the City’s Well Interference Standard Operating Procedure, Permit to Take
Water Requirements, upcoming water supply projects and the Terms of Reference for the
Committee. The purpose of the review was to inform new members who may not have been

Appendix K: Source Water Protection
The third annual report summarizes information requested from the Risk Management
Official by the Source Protection Authorities, as required under section 81 of the Clean
Water Act, 2006 (CWA). The report outlines activities undertaken by the City of Guelph in
2019 to protect municipal drinking water sources. Source Protection is one component of
the multi-barrier approach to ensure clean safe drinking water.
The Lake Erie Source Protection Region is one of 19 in Ontario created to implement
drinking water source protection planning under the Clean Water Act, 2006. The region
includes four watersheds, called Source Protection Areas (SPAs) in the Act:
• Catfish Creek
• Grand River
• Kettle Creek
• Long Point Region
The City of Guelph is part of the Grand River SPA and has a representative who sits on the
24 member Lake Erie Region Source Protection Committee (SPC). The SPC meets about four
times a year to discuss and implement matters related to program implementation. The City
of Guelph is an active participant along with other municipal representative who have a
stake in drinking water issues.
The Grand River Source Protection Authority will receive this information in the format they
have requested by February 1, 2020. This information may also be requested by the
Director of the Ministry of Environment, Conservation and Parks (MECP).
City of Guelph internationally recognized for Source Protection
In 2019, the City of Guelph was awarded the American Water Works Association Exemplary
Source Water Protection Award. Award winners “establish and maintain source water
protection programs that account for their unique local conditions, incorporate the interests
of local stakeholders, and reflect sustainable long-term commitments to the process by all
parties.” Established in 1881, the American Water Works Association (AWWA) is the largest
and oldest non-profit, scientific and educational association dedicated to managing and
treating water. There are approximately 50,000 members worldwide.

Risk Management Official Update
The RMO represents the City of Guelph as a municipal member of the Grand River Source
Protection Committee. The Risk Management Official (RMO), Peter Rider, was appointed
under subsection 47(6) of the Clean Water Act on May 27, 2016. The Risk Management
Inspector (RMI) Kristin Pressey, was appointed on December 19, 2017.
Threat Verification and Negotiating Risk Management Plans
The City of Guelph continued to work with a number of property owners and businesses to
verify and manage threat activities at their sites. Threats identified in the 2010 Assessment
Report total 942 within the City of Guelph. Threat verification has been completed for 409
sites, resulting in the completion of 12 Risk Management Plans (RMPs) and an additional 4
in progress. City staff continue to develop RMPs for sites with threats, including evaluating
existing practices and identifying potential missing gaps in drinking water protection. A
template developed by the City was used to make the Risk Management Plan negotiation
process less onerous for business and property owners.
2019 Annual and Summary Report
Page 173 of 182
Information related to the Source Protection Program is managed in the Local Source Water
Information Management System (LSWIMs), a data management system. This program is
used by several other municipalities in southern Ontario to manage data associated with the
Source Protection Program. The application is being updated regularly with additional
functionality as requested by the collaborating partners.
Figure 9: Risk Management Official Summary, 2019
The CWA requires a section 59 Notice for development within the Wellhead Protection Areas
(WHPAs) to determine if an application has a potential to introduce a new threat to drinking
water. A notice is required before planning and building applications can be deemed
complete. In 2019, Source Water Protection staff reviewed 361 applications and issued 167
Section 59 Notices.

Policy Implementation
The City of Guelph is the implementing body responsible for a range of Source Protection
Policies, from prohibition to negotiating Risk Management Plans (RMPs) and providing
education and outreach. There are 72 policies in the City of Guelph’s section of the Grand
River Source Protection Plan. Of these, 48 are identified as the City’s responsibility to
implement. As of January 2019, we currently have 28 policies fully implemented and 18 that
we have made some progress on. Efforts are underway to implement the remaining policies,
however, there may be certain triggers required (e.g. upon the next Official Plan update)
which will determine the pace at which some of the policies will be implemented.
Protecting Water Quantity
The City of Guelph is working closely with the Townships and staff from the Lake Erie Region
Source Protection Authority to develop a set of water quantity threat policies for the
identified WHPAs. Meetings are ongoing and it is anticipated that public consultation will be
completed by the end of 2020. The draft policies will then be submitted to the Minister of
Environment, Conservation and Parks for approval before implementation.
2019 Annual and Summary Report
Page 175 of 182
Education and Outreach
In the second half of 2019 moving into 2020, Source Water started an ad campaign to bring
awareness to the program. The campaign consisted of Guelph Transit advertisements: both
on the back and side of the bus; along with posters up at various bus shelters throughout
the City. Advertisements were also posted through various social media sites and the
Guelph Chamber of Commerce. Figure 11 below is an example of source water public
communication.
Figure 11: Source Water Protection Advertisement to Reduce Your Winter Salt Use
Staff from the Sourcewater Protection Team have worked collaboratively with the City of
Guelph Operations department staff to sponsor and support the purchase of new and
enhanced road salting equipment. The goal of this initiative is to improve the management
of road salt application within the City and to obtain a better understanding of how much
road salt is being applied throughout the City. The purchase of this state-of–the-art
equipment will allow the Operations department to develop more accurate records. This will
greatly assist both departments in developing a better understanding of water quality trends
and potential impacts to our drinking water system.
Staff from the Source Water Protection Team have also been actively involved in providing
input to a joint committee lead by Ontario Good Roads Association and Conservation
Ontario, whose mandate is to raise awareness at the provincial level of increasing chloride
trends in groundwater and the need to evaluate the effectiveness of current legislation and
best practices for winter maintenance.
Private Well and Septic System Decommissioning and Sanitary
Sewer Connection Grant Program
A primary objective of City of Guelph’s Source Water Protection Program is to protect our
existing and future municipal drinking water supplies. There are several threats to drinking
2019 Annual and Summary Report
Page 176 of 182
water that can be managed; however, unused water wells and septic systems can act as
conduits for contaminants to migrate to deeper aquifers that supply water to the
community.
The goal of this program is to provide eligible residents with grant funding to offset the costs
of decommissioning unused wells and septic systems on their property. There are several
benefits to initiating such a program, including the reduction of risk that contaminants can
enter such infrastructure and move downwards and impair or contaminate drinking water
supplies.
The grant program is comprised of two parts: A well decommissioning grant component and
a septic system decommissioning grant component. This program is intended for private
domestic residential wells and septic systems. Developers are not eligible for the grant.
Residents are welcome to apply for one or both programs depending upon their situation. All
applicants must complete and submit a Decommissioning Grant Application Form. City staff
will arrange to inspect the well or septic system before decommissioning and approve any
work to be eligible for the grant. Property owners can apply for rebates that would include
$1,500 per private well (to a maximum of two per property) and $15,00037 per septic
system decommissioned.
The Grant Program was approved by Council and initiated in the summer of 2019. Program
uptake was voluntary and dependent on citizens taking the initiative to inquire about
funding and eligibility. To date, uptake has been minimal with only one septic system and
one well decommissioned at two separate properties. More information on this program is
available for reference at the Well and Septic Decommissioning Rebate Program webpage.
Moving Forward in 2020
Efforts will continue to develop Risk Management Plans and carry out threat verifications, as
required. We anticipate ramping up efforts to educate the public about road salting and how
everyone can play a part in reducing the amount of road salt that is applied to hard
surfaces.
The Source Water Protection team will continue to pursue opportunities to educate the
public and various stakeholders on the benefits of protecting our water resources. This will
